Huh?  Why couldn't you use garbage collection with objects allocated in
shm?  The worst theoretical case is about the same programatically as
having garbage collected objects in a multithreaded program.

Python doesn't actually support that as of yet, but it could.  In the
interim, if the memory you're sharing is array-like then you can
already take full advantage of multiprocess solutions in Python.
