Several are running crafty on duals under NT4.  I run on quads 100% of
the time and usually if there is a problem in the parallel search code, it
hangs quicker with more processors.  If I see it "hang" I always fix this,
and haven't seen one in several years now.

Other things could cause problems, like a broken book that didn't download
100% correctly, etc.
