actually, with realtime-lsm, there's really no need for this, except for
some convenience. Every app can create its own RT threads these days.
The 2.4.x capabilities days are (thank gawd) over :)

Agreed. why not make it prio 98 by default then? (system timer should
still be higher i suppose). With a difference of only 10 between main
jack loop and the watchdog, it might get a little crowded :)
