Don't forget memory hotplug in your combination mix. Your ballooner fragments the hell out 
of your memory, and your hva method requires some work to keep the state updated.  Memory 
hotplug on the other hand suffers from neither of those problems.

That said, I rather like the hva method.  It's quite clever.
