Well, i'd say that a different issue. Keeping track of "old unused physical pages" and keeping track of "available virtual memory area" are clearly (to me, at least) distinct stuff.

I'd be tempted to use a datastructure i've seen somewhere else (Ephemeral State Processing, to be precise) which consist of an fixed-aging hash table, but i have not investigated if that'd really be of some help atm.
