I don't buy that last comment.  IE I spend a _lot_ of time improving
my sequential search.  Because it is the _exact_ same search I use in the
parallel version.  And I know that any improvement done in the sequential
search will also benefit the parallel version.

The threading code is 100% independent of the alpha/beta search code.  You
could spend years fiddling with how you thread, where you break things up,
what kinds of updates you do across threads, etc... without touching one line
of the base alpha/beta stuff.  You could also spend years fiddling with the
alpha/beta search stuff and never touch the threading code either.  They are
totally independent of each other.
