I suppose this could be used, but directly accessing the function pointers
in non local code seems to be frowned uppon in most parts of GTK+.  I
wasn't saying that it was impossible to do it, just that
g_object_new_valist looked fairly non trivial (about 140 lines) -- not the
sort of thing you would want to rewrite if you could help it.
