With due caution about @marssaxman's point that software is fundemantally interrupt driven, I will agree with this. I work an a real-time system that is controlled by RPC from a desktop. We claim we want to keep the real-time code small and simple. Yet I find people pushing complexity down onto the RT system even when the real-time guarantees aren't needed because the PC code responds to it using a callback driven async model. It's easier to put a non-real time for loop into the RT thread than to emulate a for loop on the PC.
