I just ran

nice ./blink -20

and it did not seem to change the jitter at all.

Well, first of all what is your program written in?

Or at the very least tell Linux that my program is the most important thing
in the world and service it above all other things.

I am trying to create a timing signal with the Pi.  It is doing it but the
jitter is pretty bad.

I have researched trying to use an interrupt but there is a pretty low limit
on how many times per second you can fire a hardware interrupt.
Too low for my application.
