 Description   

 It would be nice to evaluate if false sharing could impact performance on the PriorityTicketHolder. 

A starting place could be running ticketholder_bm with cache profiling.

It's possible there is no false sharing with the PriorityTicketHolder. However, it could be worthwhile to regain some performance of the switch from SempahoreTicketHolder to PriorityTicketHolder
