Ok, a new version of jack is there, ready for you to upgrade to :-)

Does not have your patch, it includes a patch that properly initializes
some stuff before the realtime thread is created. For some reason under
fc2 that seems to make a difference. If the patch is not included (if I
remember correctly) the realtime threads are not created SCHED_FIFO at
all, you can check that with chrt before upgrading. But pthread_create
does not complain and all the code assumes the thread has been created
just fine.
