Minor question on this patch. AFAICS there is another patch that seems
to be aiming at exactly the same use case. Jonah's Bloom filter patch.

Shouldn't we have a dust off to see which one is best? Or at least a
discussion to test whether they overlap? Perhaps you already did that
and I missed it because I'm not very tuned in on this thread.
