How about an Mnesia-like database for Python?  (Mnesia is an embedded
database for Erlang programs.)

I see in the PyLinda page that 

  * 13/1/05 - Version 0.4  
    * Removed SysV shared memory and made Unix Domain Sockets the
       default as they are quicker.

That sounds to me like the shared memory version was broken somehow.
I don't see how a socket-based approach needing context switches could
be faster than a zero-copy, all-userspace approach.

FWIW, I remember seeing a web page about someone else implementing
tuplespace in Python for his home Beowulf cluster, but although it was
written as a C extension, it didn't seem all that serious.  Found it:
