Some examples:

• Graphicals notify their device when they are destroyed, so the device can delete them from device<-graphicals and update the display.
• A window will destroy the associated Xt-widget realising the window in X.
• A char_array will unalloc the associated C-data-structure representing the text.

  NOTE: Unlink should never be called directly by the user. Any user-defined object->unlink method should invoke the method of the super-class (see object->send_super).
