"Sass" seems to be a critical component of the operating system. That process runs unless my model is asleep or needs a doctor. Have you heard of the sass-back algorithm? Don't let it run constantly because it loses its impact, but you can always pull it out when you need the sassing to just stop....

function sass-back (sass): return sass

I'm not sure why, but sass-back seems to put sass into a panic. It temporarily stops all system output while it tries to restart and initiates "stare".
