I was thinking the same, but I'm not sure how that really helps us. The
histogram is a good idea, imv, and I'll add my vote for implementing
that. If it's too expensive to do currently then we need to work out a
way to make it cheaper. The log-based histogram as an array w/ NULLs
for any empty buckets might not be that terrible.
