Priority 100 is the absolute max on Linux. When you use that, nothing else 
will stop jack in case of errors. And nothing else has a chance to run, not 
even interrupts handlers for hardware.

Using priorities above 80 seems save, above 90 there is a good chance that 
your jack-threads take up your cpu and nothing has enough priority to stop 
them...

Don't test what happens while all is well, test what happens when you have a 
high dsp-load and then a cpu-hogging client.

Have fun,

Arnold
