> zlogoutd does in fact die in response to HUP
In general, background processes run in an Athena xterm do not get a
HUP on logout. The HUP only goes to the process group which is in the
foreground at the time the xterm goes away.
Ensuring that you die on logout is a tricky thing. You can hold a
connection open to the X server and notice when it is closed, but
that's a lot of work. You can periodically check whether opening
/dev/tty works, but that's also a fair amount of work and it's ugly.
I don't have a great answer here.
