@haypo: Python 2.7 is absolute horror.
But i tried and produced a (terrible - i don't know the test
framework and that test_support stuff seems to have been changed
a lot since 2.7) 2 gigabyte+ big buffer test for 2.7.
(Of course: even though Python uses int, ZLib uses uInt.)
It took some time because i fell over #1202 from 2007 unprepared.

The (nasty) test works quite well on Apple, which is not such
a big surprise, because Apple's OS X is especially designed for
artists which need to work on large files, like video+ cutters,
sound designers with sample databases etc., so i would be
terribly disappointed if that wouldn't work!  Apple even
propagandize OS X for, and makes money with that very application
task - i really couldn't understand your doubts here.
