 Description   

We've found that, when simulating a contentious workload, in order to see consistent contention in the SemaphoreTicketHolder (the existing default), the number of queued operations increased up to 3k. The LowPriorityAdmissionBypassThreshold must be low enough that the bypass threshold is larger than the expected number of queued operations.
