No two processes may use the same user profile simultaneously.  That's 
why when starting LO, it first checks whether another LO instance is 
already running for the same user profile, and if yes, hands over its 
command line args to the already running instance and quits again.  This 
mechanism is independent of LO versions, so for a LO 4.4 and a LO 5.0 
both using ~/.config/libreoffice/4 as user profile, when one is already 
running, starting the other will re-use the already running instance 
(even though it's "the wrong version.")
