You did, but that's ok. Miscommunications make for the best dinner table
conversations. :-)
I pointed out yesterday(?) that according to the UNIX98 specs, opening a
tty is not guaranteed to be sufficient. This, combined with a comment from
the server_pty.c code, sent me on a quest to see if POSIX specified an
alternative means for setting the controlling tty.
