The basic problem is that the zipfile interface only reads and writes
whole files, so it may perform poorly or fail on huge files. At one
time I implemented a patch to allow reading files in chunks. However I
believe that the current interface has too many problems to solve by
incremental patching,

zipfile.read() does not seem to take full advantage of zlib's

But then the solution would not be portable, which would be a shame

Take a look at the pywin32 extension, which I believe has some lower

this situation. If I'm completely wrong, someone please tell me XD.
Of course, you could just make the read() a step process, reading, O
