I can't figure it out, but I am 100% sure it is needed. Let's say I have 2 actors, Root-A <-> Nested-B Root-A has a "helper UI loop", in the actor core, and front panel visible. Nested-B is a "controller". So I see the Nested-B as a "controller", and I interact via Root-A to send messaged to its queue, for example: 1) set parameters 2) run the test the "run test" inside Nested-B, just "batch send" to ITSELF some messages (they are the "test-steps", because a test is made up by N steps. Right? so Imagine each test step is just a wait (N) seconds. Suppose I want to ABORT the test. I want to send abort message in front of queue. But how? how can I flush the queue? After abort, the actor should not quit, but stay alive for another test run. In my root I should avoid sending other messages to the Actor-B loop, what is the best strategy? Disable UI controls? I a user click 5 times "run test" button, I don't want to queue 5 runs of course.

How to flush AF queue?

I agree with having a helper loop handle all the heavy lifting as being the best solution, leaving the message loop always ready to handle new messages.
