Let me give it a try today just for kicks to see how it performs.

> When all active input ports of an operator are empty, the operator either
> calls idle time handler or goes into a wait. In the later case, the wait time
> should start with 0 and increase to the configured/default idle spin time to
> handle cases when there is trickle and pour stream of tuples.
