> The daemon expression currently runs until it's killed. This ticket will add
> a new *terminate* parameter to the daemon expression that will allow the
> daemon to shut itself down when it's finished processing a topic.
> There are a couple of small changes that need to be made to allow the daemon
> to terminate on it's own:
> 1) The daemon will need to be passed the Map of all daemons in the /stream
> handler. This will allow the DaemonStream to remove itself from the Map when
> it terminates.
> 2) Logic needs to be added for the daemon to exit it's run loop if the topic
> signals it had a zero Tuple run. The *sleepMillis* value in the EOF Tuple can
> be used for this purpose. If sleepMillis is greater then 0 then this signals
> a zero Tuple run.
