[Python-Dev] zipfile module can't handle large files

[Guido van Rossum]

Please file a bug at the new bug tracker (bugs.python.org). Please add
a small self-contained code sample that shows the issue, and specify
what you would like to see instead (keeping in mind that you just
can't allocate 2 GB on a 32-bit box).
