Lately we noticed that the Kerberized telnetd we're running (it's
essentially the same one as what's still "shipped" with Kerberos 5,
but we're only using the Kerberos 4 support) was losing randomly
on our DECstations; I traced it back to the close(pty) at the end of the
getptyslave function getting a SIGHUP. Has anyone seen this before? For
the life of me I can't figure out why it's happening...
