How to stop an Akka actor (and shutdown the Akka system)

Akka actor FAQ: How do you stop an Akka actor?

I don't have time this morning to write my usual tutorial, so in short, if you want to stop an Akka actor, use code like this from inside your actor's receive method:

context.stop(self)

Or, if you want to shut down the Akka system, use the following code, again from inside the receive method of one of your actors:

context.system.shutdown()

I'll write more about this in the future, but in the meantime you can see examples of this in the Typesafe/Akka "Pi" calculating example.
