I've looked at the relevant changes on the branch, looks good to me.

One small question, does the name need to be changed to gc_remaining_count?
There are already controls based on the number of gcs, maybe we can add a
gc_remaining_ms later? Control the gc mode based on the expected time. When
the count is reduced to 0 or the gc ends and the expected value is reached,
switch back to the normal mode.

Thx,
Yangtao
