Async is not new. life has been doing it for millennia. Your heart does not stop beating while you breathe, yet both systems are interrelated. The body accomplishes this through the use of &#x27;buffers&#x27;. Pause one system long enough and the other will fail. So we have evolved a &#x27;scheduler&#x27; - the hindbrain that starts to scream louder and louder when the event queue of one system becomes too long. It might be instructive to model this in silicon. Have one cpu core be the scheduler. Have every set of interrelated processes (that are Async) register their variables with the scheduler. The scheduler then keeps track of these sets. When a variable in a set changes, pause that process for two cycles.
