I agree that the implementation of Indefinite_Hashed_Maps is probably the
culprit, but until you have an apples-to-apples comparison, you have no
complaint. (Actually, I can't think of any application that could use such a
function where the difference would prevent it from meeting reasonable timing
requirements, so you probably have no complaint anyway.)
