QCoreApplication will not quit

Followups directed to: comp.lang.python

Can someone please explain why this simple PyQt4 application never exits?

#!/usr/bin/env python
from PyQt4 import QtCore
import sys
class foo(QtCore.QObject):
	def __init__(self, parent):
		QtCore.QObject.__init__(self, parent)
		self.parent = parent
		self.end_job()

	def end_job(self):
		QtCore.QCoreApplication.quit()

if __name__ == '__main__':
	app = QtCore.QCoreApplication(sys.argv)
	myFoo = foo(parent=None)
	sys.exit(app.exec_())

This is just a very simple, cut-down example to demonstrate a problem I have 
with an application I am writing.  If I call 
QCoreApplication.hasPendingEvents(), the result is always True.  Even if I 
call QCoreApplication.processEvents(), the application still does not quit.  
It just hangs forever.

I'd appreciate some help in finding out how to make it quit.

Thanks.
Adrian.
