Message 129120 - Python tracker

I have a MacBook with 2 GB RAM.  Of course i'm a little bit messy, so an entry is half written before it comes to an ... end.  msg129091 is real life, though.

Antoine, your msg129093 patch of test_zlib.py does it (with and without fprintf(3)s).  CRC ok etc., it just works.
(Seems mmap(2) has a problem here, i would say; the mentioned bug report is from 2003, so the golden sunset watchers may need some more additional time, if you allow me that comment.)
