           wx.wxMilliSleep(10) -- adjust as necessary
           wx.wxGetApp():ProcessIdle()

I can't test the changes above right now, but take a look at
wxPython's samples/mainloop/mainloop.py program and it's wxApp's
MainLoop function. Hopefully the only problem is that you need to
completely flush the events with the "while wx.wxGetApp():Pending()"
loop and give the event handler a little kick with
wx.wxGetApp():ProcessIdle() every once in a while.
