(Circa 1970 or so)?? :) Yes, they've been considered in the past, but always rejected because the clock-based approach was entrenched in the market, and continued to perform and scale well. I've read that something like 50% of the power draw of current CPUs is related to the clock synchronization effort. Not to mention other problems caused by the necessity of clock synchronization... I think there's a good chance that an asynchronous approach will be tried again in the near future.
