cc: Check for cheap task completion sooner
Instead of using the normal 6 ms period to poll for cheap task
completion, do the check immediately after running a batch of cheap
tasks. This improves cheap task completion latency.
In order to avoid disturbing the scheduling of normal task completion,
this optimization is only performed if there are no pending non-cheap
tasks.
