It is not that much work really. Follow the example that I gave at the 
end of the second thread. You don't have to change all your tasks to 
POSIX. Only the ones that need SCHED_RR. And you can still use classic 
semaphores, message queues etc. inside them.

It didn't work for me back then, as reported in:

The bug may have been fixed, I don't know. Try pthread_setschedparam and 
see what happens.
