Otoh, I have yet to see the figures showing the CPU afinity
buys you anything in reality. We know the GIL, thats for sure
but I never saw a measureable difference binding a process
to a CPU (which is also highly depending on the OS scheduler)

I can imagine usefull applications of this - and thats for
tiny computing intense applications where you can assume
the CPU afinity keeps the program in the CPU cache.

Zope isnt by far a "tiny" application compared to the cache size
of actual CPUs.
