this is solvable too.  When time runs out, I *never* bail out of the
search until I start to search *another* root move.  I allow a 2X time
overflow here in fact, because I handle the case where the first move is
good, but the second one is going to be better.  I make sure that
whatever
root move I am "hung" on when time runs out gets searched to completion
to
see if it is better, or if it going to fail low.
