Subject: 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.
