I agree, it would only be for efficiency. I think now that the
best solution is to just store the max. If clear.. is called
with the current max, we can start at max and going downwards
we can do FD_ISSET on each number until we find something that
is set. Then we have the new max.

Maybe, but I don't like it. Are you sure there are may not be bad
things happening if the number is outside the size of the set?

Yes, I think we should be nice to the users though (: There's less
time wasted by doing it once in C than having many PHP programmers
doing it over and over again...

I'm no expert, but I really can't see why it's needed (:
