I think that they really are Bloom filters.  They match the
description for "Bloom filter" in Wikipedia.  I probably should have
just described them as Bloom filters in the header file, but I
originally learned about them from Knuth v3, and he doesn't (IIRC)
call them Bloom filters even though he cites Bloom as the inventor.
