this isn't correct.  Check this out.  I have _every_ ICC game crafty/scrappy
have ever played.  Here is a 1996 game:

[DeepViolet (2358) vs. scrappy (2177) --- Mon Nov 25, 04:13 PM EST, 1996]

This was at a time when crafty was 2550 (pentium 133 or P6/200) while scrappy
was running on my P5/75 notebook.  At this point scratchy's rating was 2800+
and the next closest human was 2500 or so.

I don't follow the 'parallel hardware' comment.  Cray Blitz used 16 cpus and
played dozens of 5 0 games with me manually operating.  In fact, we played with
the _real_ chess clock, and relied on my typing speed to not lose on time.
There doesn't have to be a big delay to get going.  DT played lots of speed
games at the various ACM events with no problems at all...

Crafty may well do that as well.  I have been looking at it to see why
this happens occasionally...
