I'm not a specialist, but inside userspace threads are not deterministic, that
means it could be 2-1-3 or 1-2-3 another time !! So you have to use mutex. The
priority (I have read the highest is up to 1Mio ????) has to do with the
scheduler behavior - which task have to schedule at first ??? But I'm not shure.
