Gene, have you tried schedtool to set the scheduling policy of the process to 
SCHED_FIFO or even SCHED_ISO? 

Before anyone asks, yes, relying on schedtool puts a little reponsibility on 
user space, but it is my firm believe that (a) you can't auto-everything and 
(b) the onus should be on the distro not the user.
