After some tinking...
Neither SCHED_FIFO nor SCHED_RR should automatically be promoted to SCHED_SOFTRR in the kernel.
* If a process knows about SCHED_SOFTRR it should use that. (example: arts should use SCHED_SOFTRR not SCHED_FIFO) Problem: what to do when compiling for UN*Xes that does not have SOFTRR. [Is there any other UN*X that have something resembling of this? What do they call it?]
* Cases where the code has not been modified should be handled by a wrapper (library). setscheduler is a weak symbol isn't it?
