/**

* @brief Lower priority of current thread.
|
|
*
|
|
* It's used by worker threads so they use up background cpu and do not stall
|
|
* the main thread If current thread is running with real-time priority, we
|
|
* decrease our priority by @c RTNICENESS. This is done in a portable way.
|
|
*
|
|
* Otherwise (we are running with SCHED_OTHER policy) 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 as of now. In this case the nice level is
|
|
* incremented on this thread by @c NICENESS.
