Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described here (it's not a Py3K issue, just something Py3K discovers): http://mail.python.org/pipermail/python-dev/2006-April/064051.html Hye-Shik Chang promised to look for a fix, so no need to fix it here. The tests that are expected to break are: test_codecencodings_cn test_codecencodings_hk test_codecencodings_jp test_codecencodings_kr test_codecencodings_tw test_codecs test_multibytecodec This merge fixes an actual test failure (test_weakref) in this branch, though, so I believe merging is the right thing to do anyway.

+\subsection{Using locks, conditions, and semaphores in the \keyword{with}
+statement \label{with-locks}}
+
+All of the objects provided by this module that have \method{acquire()} and
+\method{release()} methods can be used as context managers for a \keyword{with}
+statement. The \method{acquire()} method will be called when the block is
+entered, and \method{release()} will be called when the block is exited.
+
+Currently, \class{Lock}, \class{RLock}, \class{Condition}, \class{Semaphore},
+and \class{BoundedSemaphore} objects may be used as \keyword{with}
+statement context managers. For example:
+
+\begin{verbatim}
+from __future__ import with_statement
+import threading
+
+some_rlock = threading.RLock()
+
+with some_rlock:
+ print "some_rlock is locked while this executes"
+\end{verbatim}
