------- Additional Comments from Ada Chan <adachan at apple.com>
This patch has been revised from the previous version.	The condition of
whether we should hold off on the scavenge has changed.  We'll check whether we
need to commit any memory in the last 5 seconds.  If so, it's a sign that there
are not enough free committed pages around for the amount of allocations that
we have done recently, so we should hold off on releasing memory.
