Indeed it does, so let's not stir it up again unnecessarily!
Lee & joq on jack-devel sorted me out nicely on that one. I normally run
with LD_ASSUME_KERNEL set, but it got overlooked/omitted on one script.
Everthing seemed to be working right, but schedtool didn't show the
class as expected. It seems to be no more than a schedtool quirk when
running with NPTL (accidentally). As guided by joq,
ps -eLo pid,tid,class,rtprio,ni,pri,psr,pcpu,stat,wchan:14,comm
showed things were cool and as expected, even with NPTL.
cheers, Cal
When running jack_test4.1 with
LD_ASSUME_KERNEL=2.4.19 set, schedtool
shows all the appropriate threads as sched_iso. Without
LD_ASSUME_KERNEL set, there isn't a sched_iso thread to be seen. They
all appear to be sched_normal.

This smells much like the classic nptl-hell some jackd users
experienced. See this page:
