The default scheduling of RT pthreads is SCHED_OTHER, which means that
their priority is 0. This makes them suitable mostly for non real-time
duties. native rt_task have no default priority, since passing a
priority to rt_task_create is mandatory, but you can create them with a
null priority as well if you like.
