Yes, I have some other things run by systemd but they run from startup
to shutdown, not just during a GUI session.  Does systemd know about X
sessions?

But there's no logout 'hook' is there?  Where would I put this killall
so that it runs when I log out of the xfce4 session?

Er, no, not really.  That's exactly the problem, I have my 'daemon' on
xfce4-session-settings to start 'on login' but there doesn't seem to
be any way to stop it at logout.
