+ *          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.
