Summary: zipfile module and 2G boundary
Initial Comment:
The zipfile module currently can not handle archives that have file
headers that begin past the 2**31 byte boundary. This is really bug
#679953 all over again -- that fix didn't solve all of the problem.
Patch to CVS HEAD attached, backport candidate to 2.4.2 and
2.3.6.

[From a post to python-help]
Related to this is that zipfile raises an exception on creating a file
that's too big. It seems that the limitation should be documented or
removed.
This is from the message to python-help:
python version 4.2. the class zipfile in the module zipfile is unable
to .close() a file bigger than
2^32-1 (or whatever) bytes.
Traceback (most recent call last):
File "bk.py", line 12, in ?
zf.close()
File "C:\Python24\lib\zipfile.py", line 503, in close
zinfo.header_offset)
OverflowError: long int too large to convert to int
