    execute a command only after all subscribers have consumed their messages

      Let's say we have queue Q1 and we enqueue two messages M1 and M2. Q1 has three subscribers S1, S2, and S3. We want to execute some process P1 only after ALL subscribers (S1-S2-S3) have consumed all of their message (M1-M2). Is this something Q1 would know about (it knows once all subscribers have processed all their messages) so that on "ALL Done" event it can start P1 either directly or by enqueuing a message for another subscriber, or is this something that requires hand-written code that would keep track of who has dequeued what and execute P1 once everybody is done.
