A couple of more things.....

1. See PyQt docs "Support for Threads"

http://www.river-bank.demon.co.uk/docs/pyqt/PyQt.html#AEN523

2. As quoted from Qt docs for QApplication()....

"For any GUI application that uses Qt, there is precisely one 
QApplication object, no matter whether the application has 0, 1, 2 or 
more windows at any time."
