+ <p>
+ Set scheduler wake cleanup threshold. Default is <c>medium</c>.
+ This flag controls how eager schedulers should be requesting
+ wake up due to certain cleanup operations. When a lazy setting
+ is used, more outstanding cleanup operations can be left undone
+ while a scheduler is idling. When an eager setting is used,
+ schedulers will more frequently be woken, potentially increasing
+ CPU-utilization.
+ </p>
+ <p><em>NOTE:</em> This flag may be removed or changed at any time without prior notice.

+ Scheduler threads will now by default be less eager

+ can also be controlled using the <seealso
