+ * @param   ullNanoReq      Time to sleep, in nano seconds.
+ * @param   pullNanoRem     Where to store remaining time (also nano seconds).

+ * @remark  For relativly small sleeps this api temporarily changes the thread
+ *          priority to timecritical (that is, if it's in the normal or idle priority
+ *          classes) to increase precision. This means that if a signal or other
+ *          asyncronous event is executed, it will be executed at wrong priority.
+ *          It also means that if such code changes the priority it will be undone.
