This statement seems counterintuitive to me.  If one thread is given a higher
priority in the CPU, than the OS would need to take this into account (and not
just with PAUSE). Could you add a little debugging code to crafty and measure
how many nodes are computed by each thread on a run of your dual xeon?  I'm very
curious if it is a 40/40/10/10 split or a 25/25/25/25 split (the latter seems
more logical to me).
