I was thinking more that the EvStack mapping code could be
designed so that it could also be plugged in as a line discipline
(or part of one). If you didn't want a mapping you wouldn't
enable it. It needn't affect performance when it isn't enabled
and it needn't push the whole tty interface under EvStack

I would be one of the last to suggest anything remotely
