    I'm trying to develop code that mmaps about 18 files into a process (this is in
    python, so I'm not making the mmap calls directly from C - I'll probably do that
    experiment soon). The files are smallish - about 30MB total. (yet another
    attempt to use all my physmem :-)

    The mmap fails about 6 files in (on 3.5, on i386). On an older 3.1 system, I can
    get to about 13 files. I don't see any obvious resource limit that I'm hitting.

    Is there something obvious that I'm missing?

    Thanks,
    chris
