The session in the terminal looks like that:

zira:~/software/mpfr> emacs                                            <3:13:29
^Zzsh: exit 148
zsh: suspended  eclient
zira:~/software/mpfr[TSTP]> bg                                         <3:13:33
[1]  + continued  eclient
zira:~/software/mpfr> less src/Makefile                                <3:13:38
zsh: suspended (tty output)  less src/Makefile
zira:~/software/mpfr[TTOU]> fg                                         <3:13:42
[2]  + continued  less src/Makefile
zira:~/software/mpfr>                                                  <3:13:42

In short:

1. Run emacs[*] (with its X interface).
2. Type Ctrl-Z in the terminal to stop Emacs and get the prompt.
3. Type "bg".
4. View a file with "less"[*].
5. Quit Emacs (while "less" is still running).
6. Quit "less" (with 'q').

This yields a TTOU on "less" (see above). Note that 2+3 cannot be
replaced by the use of "emacs &".

[*] This is actually a shell function:

eclient () {
        emulate -LR zsh
        local display i
        if [[ -n $GNUCLIENT_ENABLED ]]
        then
                display="$DISPLAY" 
                for i in "$@"
                do
                        [[ "$i" == "-nw" ]] && unset display
                done
                [[ -n $display ]] && gnuclient "$@" 2> /dev/null || \emacs "$@"
        else
                \emacs "$@"
        fi
}

with GNUCLIENT_ENABLED not defined.
