  Add enough debugging information to diagnose failures where the
  HandlerBException is ignored, and fix one such problem, where it was thrown
  during the __del__ method of the previous Popen object.

  We may want to find a better way of printing verbose information so it's not
  spammy when the test passes.

  Issue 2408: remove the _types module
  It was only used as a helper in types.py to access types (GetSetDescriptorType and MemberDescriptorType),
  when they can easily be obtained with python code.
  These expressions even work with Jython.

  I don't know what the future of the types module is; (cf. discussion in http://bugs.python.org/issue1605 )
  at least this change makes it simpler.

  - Issue #2550: The approach used by client/server code for obtaining ports
    to listen on in network-oriented tests has been refined in an effort to
    facilitate running multiple instances of the entire regression test suite
    in parallel without issue.  test_support.bind_port() has been fixed such
    that it will always return a unique port -- which wasn't always the case
    with the previous implementation, especially if socket options had been
    set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT).  The
    new implementation of bind_port() will actually raise an exception if it
    is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
    SO_REUSEPORT socket option set.  Furthermore, if available, bind_port()
    will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
    This currently only applies to Windows.  This option prevents any other
    sockets from binding to the host/port we've bound to, thus removing the
    possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
    that occurs when a second SOCK_STREAM socket binds and accepts to a
    host/port that's already been bound by another socket.  The optional
    preferred port parameter to bind_port() has been removed.  Under no
    circumstances should tests be hard coding ports!

    test_support.find_unused_port() has also been introduced, which will pass
    a temporary socket object to bind_port() in order to obtain an unused port.
    The temporary socket object is then closed and deleted, and the port is
    returned.  This method should only be used for obtaining an unused port
    in order to pass to an external program (i.e. the -accept [port] argument
    to openssl's s_server mode) or as a parameter to a server-oriented class
    that doesn't give you direct access to the underlying socket used.

    Finally, test_support.HOST has been introduced, which should be used for
    the host argument of any relevant socket calls (i.e. bind and connect).

    The following tests were updated to following the new conventions:
      test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
      test_poplib, test_ftplib, test_telnetlib, test_socketserver,
      test_asynchat and test_socket_ssl.

    It is now possible for multiple instances of the regression test suite to
    run in parallel without issue.

+
+Cross-compiling on Windows
+==========================
+
+Starting with Python 2.6, distutils is capable of cross-compiling between 
+Windows platforms.  In practice, this means that with the correct tools 
+installed, you can use a 32bit version of Windows to create 64bit extensions
+and vice-versa.
+
+To build for an alternate platform, specify the :option:`--plat-name` option 
+to the build command.  Valid values are currently 'win32', 'win-amd64' and 
+'win-ia64'.  For example, on a 32bit version of Windows, you could execute::
+
+   python setup.py build --plat-name=win-amd64
+
+to build a 64bit version of your extension.  The Windows Installers also 
+support this option, so the command::
+
+   python setup.py build --plat-name=win-amd64 bdist_wininst
+
+would create a 64bit installation executable on your 32bit version of Windows.
+
+To cross-compile, you must download the Python source code and cross-compile 
+Python itself for the platform you are targetting - it is not possible from a
+binary installtion of Python (as the .lib etc file for other platforms are
+not included.)  In practice, this means the user of a 32 bit operating 
+system will need to use Visual Studio 2008 to open the 
+:file:`PCBuild/PCbuild.sln` solution in the Python source tree and build the 
+"x64" configuration of the 'pythoncore' project before cross-compiling 
+extensions is possible.
+
+Note that by default, Visual Studio 2008 does not install 64bit compilers or
+tools.  You may need to reexecute the Visual Studio setup process and select
+these tools (using Control Panel->[Add/Remove] Programs is a convenient way to
+check or modify your existing install.)

 PEP 3116: New I/O Library
 =====================================================
 
-XXX write this.
+Python's built-in file objects support a number of methods, but
+file-like objects don't necessarily support all of them.  Objects that
+imitate files usually support :meth:`read` and :meth:`write`, but they
+may not support :meth:`readline`.  Python 3.0 introduces a layered I/O
+library in the :mod:`io` module that separates buffering and
+text-handling features from the fundamental read and write operations.
+
+There are three levels of abstract base classes provided by
+the :mod:`io` module:
+
+* :class:`RawIOBase`: defines raw I/O operations: :meth:`read`,
+  :meth:`readinto`, 
+  :meth:`write`, :meth:`seek`, :meth:`tell`, :meth:`truncate`,
+  and :meth:`close`.
+  Most of the methods of this class will often map to a single system call.
+  There are also :meth:`readable`, :meth:`writable`, and :meth:`seekable`
+  methods for determining what operations a given object will allow.
+
+  Python 3.0 has concrete implementations of this class for files and
+  sockets, but Python 2.6 hasn't restructured its file and socket objects
+  in this way.
+
+  .. XXX should 2.6 register them in io.py?
+
+* :class:`BufferedIOBase`: is an abstract base class that 
+  buffers data in memory to reduce the number of 
+  system calls used, making I/O processing more efficient.
+  It supports all of the methods of :class:`RawIOBase`, 
+  and adds a :attr:`raw` attribute holding the underlying raw object.
+
+  There are four concrete classes implementing this ABC:
+  :class:`BufferedWriter` and 
+  :class:`BufferedReader` for objects that only support
+  writing or reading and don't support random access,
+  :class:`BufferedRandom` for objects that support the :meth:`seek` method
+  for random access,
+  and :class:`BufferedRWPair` for objects such as TTYs that have 
+  both read and write operations that act upon unconnected streams of data.
+
+* :class:`TextIOBase`: Provides functions for reading and writing
+  strings (remember, strings will be Unicode in Python 3.0),
+  and supporting universal newlines.  :class:`TextIOBase` defines 
+  the :meth:`readline` method and supports iteration upon 
+  objects.   
+
+  There are two concrete implementations.  :class:`TextIOWrapper`
+  wraps a buffered I/O object, supporting all of the methods for
+  text I/O and adding a :attr:`buffer` attribute for access 
+  to the underlying object.  :class:`StringIO` simply buffers
+  everything in memory without ever writing anything to disk.
+
+  (In current 2.6 alpha releases, :class:`io.StringIO` is implemented in
+  pure Python, so it's pretty slow.   You should therefore stick with the 
+  existing :mod:`StringIO` module or :mod:`cStringIO` for now.  At some 
+  point Python 3.0's :mod:`io` module will be rewritten into C for speed,
+  and perhaps the C implementation will be  backported to the 2.x releases.)
+
+  .. XXX check before final release: is io.py still written in Python?
+
+In Python 2.6, the underlying implementations haven't been
+restructured to build on top of the :mod:`io` module's classes.  The
+module is being provided to make it easier to write code that's 
+forward-compatible with 3.0, and to save developers the effort of writing
+their own implementations of buffering and text I/O.

+def find_unused_port(family=socket.AF_INET, socktype=socket.SOCK_STREAM):
+    """Returns an unused port that should be suitable for binding.  This is
+    achieved by creating a temporary socket with the same family and type as
+    the 'sock' parameter (default is AF_INET, SOCK_STREAM), and binding it to
+    the specified host address (defaults to 0.0.0.0) with the port set to 0,
+    eliciting an unused ephemeral port from the OS.  The temporary socket is
+    then closed and deleted, and the ephemeral port is returned.
+
+    Either this method or bind_port() should be used for any tests where a
+    server socket needs to be bound to a particular port for the duration of
+    the test.  Which one to use depends on whether the calling code is creating
+    a python socket, or if an unused port needs to be provided in a constructor
+    or passed to an external program (i.e. the -accept argument to openssl's
+    s_server mode).  Always prefer bind_port() over find_unused_port() where
+    possible.  Hard coded ports should *NEVER* be used.  As soon as a server
+    socket is bound to a hard coded port, the ability to run multiple instances
+    of the test simultaneously on the same host is compromised, which makes the
+    test a ticking time bomb in a buildbot environment. On Unix buildbots, this
+    may simply manifest as a failed test, which can be recovered from without
+    intervention in most cases, but on Windows, the entire python process can
+    completely and utterly wedge, requiring someone to log in to the buildbot
+    and manually kill the affected process.
+
+    (This is easy to reproduce on Windows, unfortunately, and can be traced to
+    the SO_REUSEADDR socket option having different semantics on Windows versus
+    Unix/Linux.  On Unix, you can't have two AF_INET SOCK_STREAM sockets bind,
+    listen and then accept connections on identical host/ports.  An EADDRINUSE
+    socket.error will be raised at some point (depending on the platform and
+    the order bind and listen were called on each socket).
+
+    However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE
+    will ever be raised when attempting to bind two identical host/ports. When
+    accept() is called on each socket, the second caller's process will steal
+    the port from the first caller, leaving them both in an awkwardly wedged
+    state where they'll no longer respond to any signals or graceful kills, and
+    must be forcibly killed via OpenProcess()/TerminateProcess().
+
+    The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option
+    instead of SO_REUSEADDR, which effectively affords the same semantics as
+    SO_REUSEADDR on Unix.  Given the propensity of Unix developers in the Open
+    Source world compared to Windows ones, this is a common mistake.  A quick
+    look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when
+    openssl.exe is called with the 's_server' option, for example. See
+    http://bugs.python.org/issue2550 for more info.  The following site also
+    has a very thorough description about the implications of both REUSEADDR
+    and EXCLUSIVEADDRUSE on Windows:
+    http://msdn2.microsoft.com/en-us/library/ms740621(VS.85).aspx)
+
+    XXX: although this approach is a vast improvement on previous attempts to
+    elicit unused ports, it rests heavily on the assumption that the ephemeral
+    port returned to us by the OS won't immediately be dished back out to some
+    other process when we close and delete our temporary socket but before our
+    calling code has a chance to bind the returned port.  We can deal with this
+    issue if/when we come across it.

+
+The simplest way to build this example is to use the distutils script
+'setup.py'.  To do this, simply execute:
+
+  % python setup.py install
+
+after everything builds and installs, you can test it:
+
+  % python -c "import example; example.foo()"

+================================
