Message:
This CL uses idle notifications to make kMaxIdleCount incremental GC cycles
and
then to wait until the mutator creates more garbage.
A GC cycle consists of:
1. many incremental marking steps,
2. one old space mark-sweep-compact,
3. many lazy sweep steps.
It works well with low-frequency idle notifications (>100ms) and is needed
for
this CL http://codereview.chromium.org/8519001/ which sends idle
notifications
when the user is idle.
High-frequency idle notifications can be enabled by tweaking the constants
and
heuristics, but first we need to land these two CLs without performance
regression.
Description:
Start incremental marking on idle notification (second version).
