I'm sure this little regression will get fixed up as the dust settles. My role was the easy one, that of hound.. all you need is spare cycles. The good news from hunting excursion is that what the reporter's probe did was to validate the DELAY_DEQUEUE mechanism as being a genuine QOS improvement. The reported QOS regression was per measurement the DELAY_DEQUEUE progression going missing when all cycles expended between the most recent inflection point event and pulling of payout lever were banked nanoseconds before the real deal inflection point, the preemption decision. -Mike
