it has been done.  Don D. had a parallel version of mtd(f) running and
it has some interesting characteristics.  But, if you have to do a bunch
of the searches, it suffers from the same problem it would on a single
cpu...  I think this works for certain approaches only, and large positional
scores are not a good idea, at least from my experience, which is not as
much as several others here that are really using mtd(f).
