You can use "taskset" on Linux (schedutils package). However it is somewhat 
a mistry about the overhead when you don't tie a process to a particular 
CPU. The current Linux scheduler tries to keep long-running processes on 
the same CPU instead of migrating them from one CPU to another one. The 
basic
rule: 1 CPU per major process (ZEO client, ZEO server etc).
