You talked that switching to power law distribution of allocation 
sizes would allow this to be done without using huge amounts of memory or runtime.


But in general we are not that constrained by memory and runtime requirements,
we could spend much more resources in generating a distribution that
will be used.

In current case trying to be clever would not help anything, see
following pattern why:
