--- Comment #1 from Jilles Tjoelker <jilles at FreeBSD.org> ---
It looks like libthr does not have any support for RTP_PRIO_IDLE either.
Perhaps this is because the risk of a non-idle thread getting blocked by an
idle thread is high (for example, if an idle thread has locked data structures
used by malloc()).

A workaround is possible by calling rtprio_thread() manually using the id from
pthread_getthreadid_np().
