+ <p>Set scheduler wakeup threshold. Default is <c>medium</c>.
+ 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.
