Xpra: Ticket #1004: osx client locks up in mmap code

The easy solution is just to disable mmap, but I would rather figure out why this code suddenly stopped working (the code has not changed for a very long time). Could be related to a recent upgrade of Pillow, numpy or Cython?

Adding print statements, I can it getting stuck on os.write(fd, b'\x00'), and it only resumes when the server disconnects the client because of the connection timeout.

priority changed from major to minor
status changed from new to assigned

I don't have time for this, so r10846 disables mmap on osx and win32 so I can move on.

r15010 restores mmap on osx as I can't get it to misbehave any more, and also adds support for mmap on win32.

I don't think it is particularly useful on osx, but on win32 one could conceivably have concurrent sessions? (does MS Windows handle that in a meaningful way?)
