Well, efficiency is not a concern here (unless you mean programmer
efficiency ;-)

Call gtk_widget_destroy() but be aware that by default a delete_event
already results in a gtk_widget_destroy() so if you do it manually it will
happen twice; two destroys leads to memory corruption and possibly a
segfault eventually.

You might read what my book has to say about this,
developer.gnome.org/doc/GGAD, chapter 3 on GTK and the GtkObject chapter
will both help.
