Waiter does not spuriously notify on index which is subject to And operation
info: |
AddWaiter ( WL, waiterRecord )
5. Append waiterRecord as the last element of WL.[[Waiters]]
6. If waiterRecord.[[Timeout]] is finite, then in parallel,
a. Wait waiterRecord.[[Timeout]] milliseconds.
b. Perform TriggerTimeout(WL, waiterRecord).
TriggerTimeout( WL, waiterRecord )
3. If waiterRecord is in WL.[[Waiters]], then
a. Set waiterRecord.[[Result]] to "timed-out".
b. Perform RemoveWaiter(WL, waiterRecord).
c. Perform NotifyWaiter(WL, waiterRecord).
4. Perform LeaveCriticalSection(WL).
