Too complex. I would say "wake up a recent process, and let the scheduler
try to figure out what CPU is the most advantageous".

If you have idle CPU's the choice is pretty much always going to be to try
to get a new CPU for the new connection - regardless of where the cache

If you don't have idle CPU's, that means that somebody else filled your
CPU already, and you might as well just try to find the most recent
process and if possible re-instate it on the same CPU it was on last time.

So I think you're right in theory, but wrong in practice, and that Andrea
is right in practice and wrong in theory.
