1) On linux you must be running as root in order to be able to set SCHED_FIFO. The code is written to silently revert to non-priority scheduling if EPERM is returned.

I am curious. Is it possible to specify scheduling priorities for threads,
even if process global strict FIFO scheduling of isn't permissible?

It is a very good idea I think to have some sort of prioritized scheduling
for the threads even if it isn't perfect. I know that UNIX can prioritize
time slicing of processes, but perhaps this can't yet be applied to
individual threads?


pthread priority scheduling does not guarantee very much.
I don't see any easy OSI way to guarantee anything about scheduling.
