I've also had this problem with 386/ix, when a getty in the LOGIN state
dies abnormally.  A 'who -a' shows LOGIN and xyzzy both on the port, but
it gives an exit status for LOGIN.

I'd call this a bug (and I will bug-report it too).  The problem occurs
with any utility that calls getlogin(3C), including mail, etc.
