I really wish people had just done case-folding as a slow case, and
not used the hash at all.

Does that mean that you have to walk the directory linearly? Yes it
does. But that's my point: you shouldn't optimize for the idiocy of
case-folding. You should optimize for the sane case, and actively try
to discourage people from doing stupid bad things.

Oh well. Too late now.
