I think the 'me not testing' is a good idea, particularly since I already did it
on the three games Vincent sent.  But the hardware is a big issue, because in
that event Bionic played on a dual CPU overclocked to something over 500mhz.

The SMP search alone will produce non-deterministic results with enough
frequency to cause consternation.  And then there is crafty's time allocation,
which means that on some moves it could take 10+ minutes on a 'whim'.
