We want this to become the default actually. Currently the semantics of
rc-local still block us from doing that. But ideally gdm would popup a

and without waiting for any other services.

We can spawn the full set of userspace services (reasonably complete
GNOME session) now in less than 1s. I doubt anybody else has been
capable of doing anything like that in this time so far.
