Anyone know how to redefine what the File>Quit menu item does on

I am trying to convert a cross-platform application to use Twisted,
and unfortunately this seems to make the pre-existing Quit menu
item on MacOS X do *nothing*. I can't quit the application without
using ctrl-C or closing the root window (not an option for this
application).
I have tried to configure that menu item, but tk does not seem to
know that it exists (the index of the last menu item is too small).
Any suggestions would be most welcome.

The pre-defined "Quit" menu entry that comes with Tk/Aqua is in the
application menu, not the file menu. In my two Python/Tk apps,
hitting "Command-Q" quits them without any code on my part--Tk is
invoking the standard "quit" event.
That is the one I meant (as you surmised).
The normal Quit menu item has always worked fine for me until I
switched to using Twisted framework. Now it does nothing.
If...you are talking about the "Quit" entry in the app menu, try
something like this:
self.bind('Command-Key-Q', lamdba event: sys.exit())
What should self be to bind this application-wide (for all windows and
widgets)? Root doesn't seem to accept key events.
(Also, although this is much better than nothing, presumably it will
not actually support the Quit menu item? If so, I hope to find a more
thorough solution.)

P.S. here is a minimal Twisted/Tkinter application that cannot be quit
normally:
import Tkinter
import twisted.internet.tksupport
root = Tkinter.Tk()
twisted.internet.tksupport.install(root)
reactor = twisted.internet.reactor
reactor.run()
Whereas the following minimal non-Twisted application quits normally:
import Tkinter
root = Tkinter.Tk()
root.mainloop()
