Have you looked into HOARD?  It uses per-process pools, but it's roughly 
the same concept.  Still, for games I can see it being useful to ration 
the memory a subsystem has available via a fixed-size pool.

We should be able to have the same for D, though a general solution 
would be reliant on the type system to determine which pool to allocate 
from.
