No, I’m not a big fan of having to write a comment “you would normally not do this” inside a piece of code which is meant as a best practices template. The sleep is simply neither reliable nor nice.

Shutting down the ActorSystem when you have determined that you’re done is exactly the right thing to do, and my code does just that. I haven’t looked closely at the g8 template in a while, maybe that needs to be fixed.
