AIUI that just helps when X starts up. When hal goes down, we'll just
get the NameOwnerChanged event with null new_owner, and wait forever for
it to come back up? I might just be misunderstanding how dbus
activation works though, I have no idea if anything keeps track of
active connections to hal when it goes down to restart it. Or if we get
disconnected from the bus somehow when that happens?
