I'm more than a bit skeptical of that claim.  Under what
circumstances (other than a really awful hash function,
perhaps) would it make sense to not use equi-sized hash
partitions?  If you can predict that more stuff is going
to go into one partition than another, then you need to
fix your hash function, not invent more complication for
the core partitioning logic.
