Without the GPL'd trivial check of being a subshell - i.e., this test
needs to be added before it can be shipped, a ~/.zlogout could look like
this:

    if  [[ -z ${SSH_CONNECTION-}${TMUX-}${debian_chroot-} ]] &&
        [[ ${0##*/} != (-su|su) && -x /usr/bin/clear_console ]]
    then
        /usr/bin/clear_console || :
    fi

The first line is mainly used to avoid accessing the hard disk and
spawning a new process in some common cases - only the check for an
empty ${debian_chroot-} might be required, depending on the actual
implementation of schroot et al.

Also using [[ ${TTY-} != /dev/pts/* ]] would avoid running clear_console
in other cases and possibly make checking ${SSH_CONNECTION-} and
${TMUX-} obsolete.
