JMRI: Threading

The initial threading model for JMRI is quite simple: Everything interesting happens in the GUI thread. For example, once a 'message', e.g. a LocoNet packet, is accumulated in a separate thread, the message is processed in the GUI thread via:

	// message is complete, dispatch it !!
	{ 
	final LocoNetMessage thisMsg = msg;
	final LnTrafficController thisTC = this;
	// return a notification via the queue to ensure end
	Runnable r = new Runnable() {
		LocoNetMessage msgForLater = thisMsg;
		LnTrafficController myTC = thisTC;
		public void run() { 
				log.debug("Delayed notify starts");
           		myTC.notify(msgForLater);
			}
		};
		javax.swing.SwingUtilities.invokeLater(r);
	}

This can't work forever, however, so we're working on a new threading model.
