Jason Evans b0d2a38b86 Bug 431739: Limit dirty page purging, r=benjamin ... Limit dirty page purging so that it terminates once the number of pages is no more than half the limit. Add a separate tree to track arena chunks that contain dirty pages. This substantially improves worst case allocation performance, since O(lg n) tree search can be used instead of O(n) tree iteration.		2008-06-20 10:34:42 -07:00
