      As part of SERVER-72067 we had to implement the TicketPool class using raw Linux futex syscalls due to not having C++20 atomics at the time.

      These calls should go away in order to use C++20 atomics once we can use them in the codebase in order to enable cross-platform usage pof the class. Right now these calls block PriorityTicketHolder from being multi-platform since they are tied to Linux.

      Places affected by this have been tagged to this ticket in the comments.
