The analytic part of me wonders if it's truly a "correct" solution: is there a genuine guarantee that the shell session will close and SSH will close the connection gracefully in 5 seconds? In practice, this should always happen, but it's probably still technically a race just like before. Just an academic exercise, though. Paul
