The dbus-launch instances are the ones that are started by the system, PID 
937 above. DBUS may start other instances for handling various things. The 
same as sendmail starts another instance for each connection. I have used 
dbus-launch on a headless system to allow multi terminals to control the 
same jack server using "dbus-launch screen". screen is a terminal based 
session manager.
