To check if it was indeed a thread problem, I repeated my tests
using Zope-2.4.0 and python 2.1.1
First I did a default python compilation (using libc_r) and then
using pth (GNU portable threads)

Using the program I sent on my previous email and a hit rate of 100
I got
libc_r: 243 sec, 28 real hits/sec
pth: 15 sec, 36 real hits/sec

So, I guess there is some problem on libc_r

PS: I did the same on OpenBSD and had similar results
