Well, the g_object_unref() happens in guile's garbage collector.

So, there are two situations:

a) The window has been created in guile (using (make <gtk-window> #:type ...))

b) The window has been created and returned by a C function.

However, I think in both cases it's reasonable to just unref the window and not
destroy it - garbage collection may happen at any time and only indicates that
the scheme side is "done with the object" (ie. doesn't need it anymore since it
can't be accessed anymore from scheme).
