Just to make life interesting, someone went in and changed all the URLs for messages in the Python mailing list.  Here's the new URL for the message which contains the repro instructions:

http://mail.python.org/pipermail/python-list/2009-February/1192951.html

The URL which represents the reported behavior in that message now points to a machine which has been upgraded to Python 2.7, not 2.6 as reported in the repro instructions, but the behavior is still the same.  Of course, these instructions won't be useful forever, because the Debian server which is running Python 2.5 (to show the previous behavior) will (I assume) eventually move on to a later version of Python itself.  But for now the repro instructions are still valid.
