I got:

REALTIME: 73.6744
REALTIME: 22.4142
REALTIME: 21.4316
REALTIME: 22.3956

on four successive tries with Pd version 0.40.3-extended-20070905 on WinXP 
with dual Pentium 4 2.4GHz. I guess the first time loaded it into the disk 
cache or something like that. Anyway it seems like the other cpu is just for
