Looks nice. The lack of testing results is conspicuous ;)
It only really solves the problem in the case where
size-of-inactive-list < size-of-working-set < size-of-total-memory
yes? In fact less than that, because the active list presumably
doesn't get shrunk to zero (how far *can* it go?). I wonder how many
workloads fit into those constraints in the real world.
