Interesting. I will try that. And I won't send any more ShutDownMessages :) Though I should add that each CometActor is doing a lot of processing. So I it would be good if I could shut one down somehow when the user searches on a new term. Timeout won't work because there is no way to know how long it will take.
Maybe I could just kill all the actors directly that are doing the processing.
