yet another way to communicate between processes

How many ways can processes communicate?
- Message passing, obviously.
- Going outside Erlang, e.g. through files, sockets, pipes, etc.
- 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.
