Please remember that we have deferred enabling the
kill-processes-on-logout setting until at least F26. 

How is your session timeout implemented? If it's $TMOUT in bash, that
shouldn't affect the _running_ command. Does it let you leave
long-running processes with screen or tmux?

I believe it's a setting in sshd. I will have to learn to run many things in tmux/screen: certainly dnf, but also all the science codes that we normally do. Actually, this will build our character: currently we kind-of depend on getting lucky if the command happens to run in background or knows to put itself in background on receivng a HUP.
