Problem is that idprio isn't safe. I used to idprio the rc5client, but
within a day or do the machine would lock up. Rc5client would get a
lock on the root of the filesystem at idprio, and if there was another
process running at 100% CPU, rc5client would never get a chance to
unlock, causing all the other processes on the system to hang.
