Take a look at rtprio(2), giving yourself a realtime priority will
guarantee you the CPU until you explicitly release it (or another higher
priority realtime process comes along). I'm not sure if the same
deadlock potential that exists with giving a process an idle priority
exists due to locking in the kernel, although I see no mention of it in
the man pages. It's definitely something I'd be wary of, though.
