Description Mark Hahnenberg 2012-04-13 11:10:50 PDT
Currently we schedule our GCActivityCallback timer at the end of a collection. This is not an accurate picture of small amounts of allocation, which is the timer's purpose in the first place. This can cause some extra unnecessary full GCs as well as wasting some memory if we haven't done a collection recently. We should move the scheduling to the allocation slow path, which would mostly mitigate these issues.
