[PyQt] QThread not exiting

[Kerri Reno]

OK, I took out all the GUI elements, but I still can't get the QThread to
exit:

from PyQt4 import QtGui, QtCore
import time, sys

class BusyThread(QtCore.QThread):

    def __init__(self,parent):
        QtCore.QThread.__init__(self,parent)
        self.exiting = False
        self.run()

    def run(self):
        print 'got here'

        while not self.exiting:
            print 'inc'
            self.sleep(1)
        return

    def destroy(self):
        self.exiting = True
        self.wait()

class Menu(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)

        self.show()

        t = BusyThread(self)

        time.sleep(5)
        t.destroy()

def main(args):
    app = QtGui.QApplication(args)
    mainWindow = Menu()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main(sys.argv)


TIA, Kerri
