Here's a straight wrapper around the OSSP mm shared memory library:

http://70.103.91.130/~michel/pymm-0.1.tgz

I've only minimally tested it on AMD64 linux.  It exposes mm shared
memory regions as buffers and only wraps the "Standard" mm API.  Hacking
the Python memory system to put objects in shared memory is too deep for
me.  Included is a test that uses cPickle to share object state between
forked processes.  It needs a lot more testing and tweaking but it works
as a proof of concept.
