I’m splitting this review into two reviews: 
(1)	This review will be repurposed solely for the fixes to the new waitcnt pass and a new test; no changes to those fixes; so I’m going to consider those fixes accepted.
(2)	The second review will be to turn the new waitcnt pass on by default. I'll give folks a chance to weigh in on that before moving forward with it.
