I used to think that Thread.yield() did the trick, and it did in one
working example I had. 

But then I used the exact same code in a piece of production code, and
it *didn't* work - mouse movement (ie, a Gtk event) required. Grr.

I recalled a comment someone made on IRC, and in a flash of inspiration,
speculated that if a GtkTimer was running, maybe it awakening would
cause an event which would get the main loop to fire.

This seems to work.

Code snippet:

   Timer _ticker = null
   int INTERVAL = 50;
...
	_ticker = new Timer(INTERVAL, new Fireable() {
		private long	last;

		public boolean fire() {
			long now = System.currentTimeMillis();
			System.err.println("Timer fired. Elapsed " + (now - last) + ", compared to interval "+INTERVAL);
			last = now;
			return true;
		}
	});
	_ticker.start();


I know others have discussed the fundamental bug lurking down in the way
that CustomEvents is hooked into the main loop, but I don't off hand
know what that diagnosis is.
