If you only call the function to destroy the dialog after your long
subroutine, it will only be destroyed after the subroutine, naturally.
You must call gtk_widget_destroy before calling the subroutine. Besides,
it might be necessary to use a while (gtk_events_pending())
gtk_main_iteration(); loop after the destruction for the widget to be
removed from the screen, but I'm not completely sure. But try it.
