How many ways can processes communicate?

  - Message passing, obviously.

  - Going outside Erlang, e.g. through files, sockets, pipes, etc.

  - ETS

  - Hipe lets you destructively update binaries

Today, I saw a new one: (ab)use erlang:process_info(Pid, dictionary) to
read another process' process dictionary. user_drv:interfaces/1 does it.
