    New tests for basic behavior of smtplib.SMTP and
    smtpd.DebuggingServer. Change to use global host & port number
    variables. Modified the 'server' to take a string to send back in
    order to vary test server responses. Added a test for the reaction of
    smtplib.SMTP to a non-200 HELO response. [GSoC - Alan McIntyre]

    Moved all of the capture_server socket setup code into the try block
    so that the event gets set if a failure occurs during server setup
    (otherwise the test will block forever).  Changed to let the OS assign
    the server port number, and client side of test waits for port number
    assignment before proceeding. The test data in DispatcherWithSendTests
    is also sent in multiple send() calls instead of one to make sure this
    works properly. [GSoC - Alan McIntyre]

    Added tests for asynchat classes simple_producer & fifo, and the
    find_prefix_at_end function. Check behavior of a string given as a
    producer.  Added tests for behavior of asynchat.async_chat when given
    int, long, and None terminator arguments. Added usepoll attribute to
    TestAsynchat to allow running the asynchat tests with poll support
    chosen whether it's available or not (improves coverage of asyncore
    code). [GSoC - Alan McIntyre]

    When running asynchat tests on OS X (darwin), the test client now
    overrides asyncore.dispatcher.handle_expt to do nothing, since
    select.poll gives a POLLHUP error at the completion of these tests.
    Added timeout & count arguments to several asyncore.loop calls to
    avoid the possibility of a test hanging up a build. [GSoC - Alan

    Allow the OS to select a free port for each test server. For
    DebuggingServerTests, construct SMTP objects with a localhost argument
    to avoid abysmally long FQDN lookups (not relevant to items under
    test) on some machines that would cause the test to fail. Moved server
    setup code in the server function inside the try block to avoid the
    possibility of setup failure hanging the test.  Minor edits to conform
    to PEP 8. [GSoC - Alan McIntyre]

    Handle errors when generating a warning.
    The value is always written to the returned pointer if getting it was
    successful, even if a warning causes an error. (This probably doesn't matter
    as the caller will probably discard the value.)

    Will backport.
