:) I got a little worried when I read the post, because I use futility pruning
in q-search too, and I was sure that Hsu had done more testing on this than I
had. On the other hand, I knew that you must also have done a lot of testing
that is at least as valid as Hsu's. When you tell me that he later "saw the
light", it makes me even more comfortable in doing it :)
