You can change the niceness of the process with the "nice" command.
There's preemption in the Linux kernel, but I don't know how to make it
happen.

Subject: [AFMUG] OT Raspberry PI
Anyone know how to get my program to run on bare metal?
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.
