Precondition: Incremental garbage collection must be currently active Finishes incremental garbage collection, unless in a critical section Code entering a critical section is expected to check if we need to force a gc completion, and to trigger the gc again if necessary when exiting the critcial section. Returns true if the gc cycle completed, false otherwise.
