Returns an estimate of the number of threads waiting for the given guard to become satisfied.
Note that because timeouts and interrupts may occur at any time, the estimate serves only as an
upper bound on the actual number of waiters. This method is designed for use in monitoring of
the system state, not for synchronization control.
