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.

 Sometimes, it is desirable to ``uninitialize'' Python.  For instance, 
 the application may want to start over (make another call to 
 \cfunction{Py_Initialize()}) or the application is simply done with its 
-use of Python and wants to free all memory allocated by Python.  This
+use of Python and wants to free memory allocated by Python.  This
 can be accomplished by calling \cfunction{Py_Finalize()}.  The function
 \cfunction{Py_IsInitialized()}\ttindex{Py_IsInitialized()} returns
 true if Python is currently in the initialized state.  More
 information about these functions is given in a later chapter.
+Notice that \cfunction{Py_Finalize} does \emph{not} free all memory
+allocated by the Python interpreter, e.g. memory allocated by extension
+modules currently cannot be released.
