Not really. It's certainly intended for the basic "fan out m tasks to n workers, and the fanout producer wants to know when they're all done" and can be abused for some more, but I don't think it does anything to help with the "consumer died, I want the producers to be able to know this rather than just continuing to push messages into a queue forever" case.

I've written wrappers to handle things the way I want, but it always feels like a bit of a hack. (Usually I use a stop sentinal internally and reach inside to unbound the queue before I send it to avoid blocking). Just wish it were built in.
