Also, unlike the formats that use intrinsics.c, this format will benefit 
from a reduced binary_size (just the one 32-bit int that is checked in 
cmp_all()), and a "linkedin" version of that would probably perform way 
better than our current one, with six million hashes. This would be 
trivial. Maybe I'll try it out later unless someone else do.
