Err, yes, I'm sort of surprised that's in the docs at all.

The point of having an upper-limit is to put an upper bound on how
much memory monotone has to use.  1M seems a bit large for this
purpose, and I'm astonished if you actually have to go to 1M to get
the benefit.  Could someone run timings at different block sizes
and pick one that gives most of the speed benefit without being huge?
