Calling
Waiting.resume()
when it had already been resumed would raise an exception. Here, the method is made idempotent by checking first whether the future has already been resolved. This fix ensures the behavior matches the behavior of the other state transitions: callingplay
on an already running process and callingpause
on an already paused process isn't rising any error.
