Which thread(s) do the tuple fanout?

Which thread(s) do the tuple fanout from a source blot to the subscriber bolts please.

Thanks
Madhav.

Each bolt/spout has 2 threads of their own.  In one thread the bolt/spout executes on.  A second thread then batches/routes the tuples where they need to go.  This may be putting them in the input queue for another bolt/spout in the current worker or putting them on a queue to be sent to a different worker.
