I committed a change to inhibit window-configuration-change-hook there.

There's another possible problem: x-create-frame sets the
background-color parameter prior to the frame being put on Vframe_list.
IIUC, this parameter needs to be set before we can consider the frame
live, because the frame size calculation depends on the default face,
which may in turn depend on the background mode.  But setting the
parameter causes a Lisp call to frame-set-background-mode, so we can in
principle get in trouble if the user redefines or advises that function.
But that's a sufficiently obscure corner case that we can leave it for
post-24.1, I think.
