Not still if it still happens, but at one point {I seem to remember} Crafty
would analyze the book moves for a fraction of the play time of a normal move
(about 10% if I recall correctly) just to ensure that the book move wasn't a
horrible blunder.

Eventually, opening books will be moot, because the computers will think deeply
enough to render them useless.  Probably a few years away yet.  But if (for
instance) you can see clearly 20 plies away, it is probably foolishness to trust
in the choices given by a human created opening book.  The machine estimations
will be better.
