This sounds like a bug. Could it change the KSEG which called the rtprio 
so there would be some deterministic behaviour to the rtprio if used in 
threaded program? So I take it from this that rtprio is also broken for 
libthr?

I fail to understand the value of being able to point to other threads 
for priority setting? Or are you talking about a facility which would 
exist below the rtprio call?
