Wait, what you observe here is that the low prio task inherits
scheduling parameter from the high prio task. The default value for the
inheritsched attribute is PTHREAD_INHERIT_SCHED. So, if you want to set
explicitely the scheduling parameter, you should call
pthread_attr_setinheritsched(&attr, PTHREAD_EXPLICIT_SCHED);
