Something like that. Well, I would also like to eliminate 
differences based on different memory caches between machines.

In addition, if the profiler could eliminate the randomness of 
the benchamrks that results from memory aligment, context 
switches and dunno, that would obviously be a big plus for 
automatic testing.

Sounds worth a look. Thanks!
