Note that "delete_event", like all signals ending in "event", has
a gboolean return value, meaning in this case:

 TRUE -  I handled the delete event, don't do anything
 FALSE - I didn't handle it, do the default action (destroy the
         window)

So, if you use a callback returning void, the behavior will
be random.
