Thanks for bringing this up, I was unaware of the issue. I don't know 
much about what advantages this brings, i e why it was turned on in the 
first place (will try to figure out during the day).

In the same breath though, I'd like to say that I have had 
plans/thoughts about contributing some piece of code to jackdbus (and 
possibly ffado as well) that uses rtkit to get real-time prio instead. I 
assume that will solve this issue as well, at least for dbus-enabled 
versions of jack. What do you folks think of that?
