Many thanks for this explanation; it looks good.  In principle,
however, I still think this is pretty tricky and so it would be nice
if libguile could offer some help here.  So if it is possible to
generalise this into something not GtkObject-specific, it would be
nice to provide this as a set of libguile library functions.
