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...
