-/* Lower priority of current thread.
- *
- * It's used by worker threads so they use up "bg cpu" as it was really intended
- * to work. If current thread is running with real-time priority, we decrease
- * our priority by 5. This is done in a portable way.  Otherwise we are
- * running with SCHED_OTHER policy and there's no portable way to set the nice
- * level on current thread. In Linux, it does work and it's the only one that is
- * implemented.
