Set scheduler wakeup threshold. Default is medium

The threshold determines when to wake up sleeping schedulers when more work than can be handled by currently awake schedulers exist. A low threshold will cause earlier wakeups, and a high threshold will cause later wakeups. Early wakeups will distribute work over multiple schedulers faster, but work will more easily bounce between schedulers.
