Hmm, I'm curious as to what categories your allocator
divides memory users in. Is it just plain swappable
vs. non-swappable or is it fragmentation-causing vs.
fragmentation sensitive or something entirely different?

Btw, I'm working on version 2 of my zone allocator design
right now. Maybe we want the complex but complete version
for 2.3...
