Read this as "tacos," came expecting some pointlessly quirky OS filled with taco references (perhaps arguments are "fillings", passed to objects called "shells"), am now very disappointed
There is at least an OS like environment called Nachos (Not Another Completely Heuristic Operating System) used many moons ago in the University OS class.
Tacos are an embarrassingly parallel problem after all. It makes sense TacOS would naturally be a thing. It might even need to be hard real time because hangry customers can get a little cagey.
