@haypo: Well i told you i have no idea. These bots are 32 bit?
I'll attach 11277-27.3.diff which does @skipUnless(not 32 bit).
Note i'll test against >_4G - does this work (on 32 bit and in
Python)? A pity that Python does not offer a 'condition is
always true due to datatype storage restriction' check?!
And i don't think it makes sense to test a _1GB mmap on 32 bit at
all (but at least address space shouldn't exhaust for that).
So, sorry, also for the two bugs in that two-liner, but very
especially the 'm' case.
