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.
