Hi Roland, Thanks for you thoughts on this.
In respect of the actor sending the messages, during the time it is iterating over it's children it will not be able to handle any new messages that arrive. Does the actor selection behave in the same way i.e. synchronously in the thread being used by actor to process the original message, or is the actor selection performed asynchronously?
