Well, it appears I was way off base. My main task is SCHED_RR, and my
child tasks put themselves into SCHED_OTHER. I didn't have any realtime
groups configured, so it was bailing out in the first conditional in

By also having the parent put the children into SCHED_OTHER, my testcase
will handle both cases (parent or child runs first) and everything seems
to be working fine.
