Cross-process dictionary/hashtable

[Sandra-24]

A dictionary that can be shared across processes without being
marshaled?

Is there such a thing already for python?

If not is there one for C maybe?

I was just thinking how useful such a thing could be. It's a great way
to share things between processes. For example I use a cache that
subclasses a dictionary. It would be trivial to modify it to work
across processes by changing the base class and the locking mechanism.

Thanks,
