Maxent training hangs GUI

When training a maxent IRTG from the GUI, the GUI can become unresponsive after training is completed. I have seen this happen when training a Geoquery grammar (340 rules, with a RuleNameFeature for each rule) on a Geoquery training corpus (500 instances).

Furthermore, the progress bar that shows during training only updates occasionally, not fluidly.

I suspect this is because the Swing EDT receives a lot of events during training that the invokeLater in withProgressListener never executes.
