There must be. Look at our telephone system. It's practically
   crash proof. Why? Erlang. It handles concurrency processing
   perfectly. None of the processes interfere with each other. They
   pass MESSAGES to each other, but they each retain their
   identities.

   Independence of identity while only passing messages is the key.
   As soon as you get statistics involved, and people getting
   lumped together as numbers that lose their individual
   identities, well, then there's problems.
