System type, version: (RT/PC) Version 6.0R; maybe vax too.
I verified that my previous suspition was correct by writing a script:
#!/bin/csh -f
while (! -e /tmp/a)
sleep 5
end
echo "Done"
and running it as testuser: /usr/tmp/script &
and then logging out. When the workstation deactivated, the cursor
sat at the bottom of the screen with no messages printed as described.
The fix is simple: add this line
ioctl(1, TIOCCONS, 0);
to the end of cooked_mode() in toehold.c. I think it only needs to be
added here, but it wouldn't hurt to add it to raw_mode() too, I
suppose.
I built a version of toehold with this change (line added to both
places) and installed it temporarily on a public workstation. It did
indeed solve the problem. Since we can't conveniently fix the more
fundamental problem of lingering processes, perhaps this fix could
make it into 6.1? Since xterm -C for a login xterm has worked, I have
seen this problem every day in the public clusters.

P.S. This is what I was doing instead of my schoolwork. Oh well.
