	Uhm... Could it be because you've shut down the application before
ever starting it?

	Note that your __init__() method -- invoked when you create "myFoo",
ENDS with a call to end_job() which invokes the framework quit() method.

	THEN after all this framework shut down, you invoke the app.exec_()
on a framework that has nothing left to run?
