Is there a protocol version number in the messages exchanged between
emacs and lisp? (I've learned the hard way--i.e. over and over again
until it's finally sunk in--that you *always* end up needing version
numbers in protocols.) Of course just having it isn't sufficient--you
then need a way to make sure the numbers get bumped at appropriate
times. But it is necessary.
