Hmmm.  Sounds good, but (1) I would need to directly access the bitmap
instead of the iterator, and (2) I would still need to clear the whole
in the iterator...

It does sound tempting because I could drop the previous patch, then
(and thus wouldn't have to worry about concurrent resetting), but I
don't think the whole implementation would be simpler.

I'll think about it, but thanks for pointing it out in any case!
