i think the problem with zero is that with -R, jackd actually needs 2
(or even 3) priorities:
* watchdog thread
* driver thread
* client threads
since it sets the watchdog to run at the stated priority, the others
need to be below it. hence ... the classic UINT_MAX-1 error. we should
probably add a check for the given priority to make sure this can't
happen. care to submit a patch?
