+ A bug in the implementation of offline schedulers has
+ been fixed. The bug was introduced in OTP-R16A/ERTS-5.10,
+ and caused work-stealing between schedulers to fail. This
+ in turn, caused work to accumulate in some run-queues.
+ The bug was only triggered when there were offline
+ schedulers in the system, i.e., when the amount of online
+ schedulers was less than the total amount of schedulers.
+ The effect of the bug got more severe the larger amount
+ of offline schedulers the system had.</p>

+ Scheduler threads will now by default be less eager
+ requesting wakeup due to certain cleanup operations. This
+ can also be controlled using the <seealso

+ argument of <seealso
