I posted a note about this to python-dev http://mail.python.org/pipermail/python-dev/2011-March/109130.html and the reaction on python-dev seems to be unanimous that Cpython is broken, and that pypy is doing the correct thing. Current discussion is about whether to just fix it, as a bug in Cpython or whether to deprecate it and then stop it, as a kindness to those who relied on it, or to backport the fix to 2.7 as well.
