Okay, but I have lots of memories of reading about problems with Python's Global 
Interpretter Lock and lightly loaded multi-processor machines.

The mailinglist archives may give more of a clue.

One thing you could try is to get a ZEO storage server up and running, then run 
up 4 or 5 ZEO clients, but each with only one thread. Then you just need to 
figure out how to round-robin them so they all appear through one port...

cheers,

Chris
