Heck, we might even consider having newPMC(N) returning a pointer to a contiguous chuck of N PMCs; this might then allow us to have good locality of reference for all the stuff in a scratchpad, for example. I dont think we can have a sensible discussion of this until the GC PDD is been released, but I thought I'd flag up the idea anyway.
