An ApplicationReplaced event is only fired when a different WebSocket
connection has taken control over an application's event stream.
If you're seeing this event and you aren't expecting it, you are
probably architecting something in your client application
incorrectly.

The application 'starts' when your WebSocket connection is made.
Asterisk uses the presence of a WebSocket connection to know that
something is able to handle the Stasis application. Without that, it
will simply bounce channels out of your Stasis application.
Because the client initiates the application, there isn't really any
need for an event. Asterisk doesn't make the decision; you do.

You should not have two WebSocket connections. You should only have a
single WebSocket connection per application.
If you want to multi-thread your client application, you should have a
single thread that reads events from the WebSocket and farms them out
to handlers. Your other application threads can then take whatever
actions they desire.
