Why is Pmw.Blt sending Destroy messages to my Toplevel?

Okay, end of crisis. This is more correct:

 def closing(event):
     if event.widget == frame._w:
         print 'closing!', event.type

Blt sends close messages because when you remove all its elements they are
little windows and they go away.

I'm sure there's a wrapper for the semiprivate variable _w, but everyone
else is doing it...
