BTW, the difference is that the delete-event is emitted when the window 
close button is clicked and destroy is emitted when the internal window 
object is destroyed.  The difference is important when you want to 
display a 'are you sure you want to close?' dialog box when the close 
button is clicked.

Are you unloading modules after the script runs?  Extension modules 
(.pyd's on win32, .so's on most other systems) are often not designed to 
be unloaded.  The same goes for normal python modules in many cases.
