They might, if we were talking about Erlang-level constructs, but
we're not.  In reality, we're talking about the mapping-key between
Game Level objects and the Erlang Processes that contain the actual
code being executed.  Pids aren't stable entities, they'll end up
changing between one run of the server and the next.  Object
References really should be unique across multiple nodes, if we want
to allow for interlinked servers in the future (or even one MU*
distributed over multiple nodes).

Now, the hard part of this bit will be managing the linkage of Pid to
Persistant ID to the state information restored from the database when
bringing it back from the dead ... that'll be the challenge.
