      The existing SemaphoreTicketHolder implementation uses timed waits in order to support interruptibility, which risks convoy effects when we have a large number of waiters. SERVER-86461 attempted to alleviate this concern by introducing jitter to the timed waits, but the convoys are still possible. Our waitForConditionOrInterrupt implementation uses a waiter list of Notifyable to support interruptible waits, so we should reuse that same idea in a new TicketHolder implementation which supports interruptibility natively (rather than timed waits).
