AkkaApplication: Clean way to shutdown and join

I'm thinking of something like Jetty's Server object, which supports:

        Server server = new Server(8080);
        server.start();
        server.join();


With Akka right now I copied akka-kernel which does:

object Main {
  val keepAlive = new CountDownLatch(2)

  def main(args: Array[String]) = {
    Kernel.boot
    keepAlive.await
  }
}


This seems like sort of a hack. A nicer solution could be: be able to wait until there are no actors running in the default dispatcher, then join the dispatcher's thread pool and exit cleanly. Something like:

 Dispatchers.defaultGlobalDispatcher.join()


With non-default dispatchers, this could also be used to wait for a set of actors to finish, just as you'd use awaitTermination on a thread pool.

Issue: some actors may need to be "daemon" actors (like "daemon" threads) so they don't keep the dispatcher alive.
