Indeed, that's the question.
When I wrote the new code for private buses, it was needed in dbus.el
(don't remember the reason). In the final code I've committed,
dbus-registered-buses isn't needed anymore on Lisp level.
I've converted it to be an internal Lisp object. Paul, is this
sufficient from your pov, or do we need more checks?
