sched_setscheduler(2)

[Bruce Dawson]

Does anyone have any experience with this system call?

I'm trying to set to the FIFO scheduler policy (for a short time of 
course), and get an "Operation not permitted" error back - in spite of 
having the image SETUID and running it as root (a bit redundant - but 
I'm grasping at straws now).

Does anyone have any ideas what could cause that message to be thrown?

I'm running on:
