Yes I've seen this too.  Why is this happening?  If the line drops while
you are composing a message in the editor (in our case micro-emacs 3.9)
then the elm and the emacs are left running on the login line.  So the
next poor sucker to try logging in has 2 processes competing for the
same port: login and emacs under elm.  If you type anything in, login
may get it or emacs may get it, and if you type ^X^C real fast to login,
emacs will exit!  Not good for my dialup users.

How is this possible?  What on earth does Elm do to allow itself to
avoid SIGHUP ?

Puzzled and displeased...
