How to use pumpThread.py so that maya does not crash each time i execute my application?

I have read in maya docs about pyqt that you should use pumpThread.py in order maya not to crash when you execute the aplication twice,but it does not say how to use it.I tried and opened and executed this script and then did pyqt scripting but maya still crashes when i execute the program twice.

please help guys

yes you need open the pumper to different thread, otherwise you will block maya. However, when you tell maya to do something TROUGH the thread you cannot assume maya i ready for the input so you must sugercoat the commands in a command cant remeber the name but its called something like executein main therad or something.

Ok,so how to open the pumper in different thread so maya does not crash anymore.

And what do you mean by paralel computing in this case? sounds cool

I was having the same problem but then I would reload the module each time.

CODE
import modulename
reload(modulename)

that prevented the crashing.

here's the main def for instantiating the window:
CODE
win = None
app = None

def Run():
    global app
    global win
    pt.initializePumpThread()
    app = QtGui.QApplication(sys.argv)
    win = MainWindow()
    win.show()
    app.connect( app, QtCore.SIGNAL( "lastWindowClosed()" ), app, QtCore.SLOT( "quit()" ) )

Run()
