We had a discussion awhile back in which the idea of *no* hint bits
was advocated, and someone (I think Robert) did some preliminary
tests that pretty much shot it down. However, I don't recall
anyone suggesting before that the four existing bits might not all
be equally worthwhile. It's worth looking into. The hard part is
probably agreeing on the test case or cases to measure behavior for.
