Zope is multi-threaded, and on certain platforms, threads are listed as 
seperate processes.

IIRC, one thread for medusa, one thread that handles all other Zope 
threads, and N threads for handling requests, where N defaults to 4. Medusa 
answers the call, one of the Zope threads picks it up and the result is 
returned by Medusa.

This way multiple requests can be taken care of simultaneously.
