No I don't currently do this. In this case I doubt it would help since the
threat extension would get overwritten at the same time the non-mate score was
written into the hash table.

I was going to add this later after I'd convinced myself that the search was
currently doing the "correct" thing - at the moment I'm convinced there's a
subtle bug somewhere instead!
