This is a problem we're facing on embedded systems. The connection to the bus 
daemon takes a couple of milliseconds -- we've got it down to 10, but I don't 
see it going under 5. If we connect to three daemons, it's 15 to 30 
milliseconds, usually at startup time.

Actually, it's worse, due to private connections. Qt cannot share its 
connections and some other services cannot either. So you end up with a couple 
more.
