	The results depend on which "equal hardware" you are using. If you get two
quad-Xeon computers (like Bob's), and match Crafty (using its SMP code) against
the same programs you will get better results for crafty, as the other programs
will only be wasting three of the four processors (and crafty will be using the
four).
