I talked to Richard, and basically, what happens is that if
you do a vhangup on Ultrix beforehand you don't get job control in the
rlogind-controlled pty. I suspect this has to do with the way ttys
are made controlling terminals on Ultrix; you could probably
dissociate yourself from the tty again afterwards, then reassociate
and it would work.
Removing the code altogether is probably a bad idea, because
it would work but lack any semblance of security; in this case,
leaving the code in would be more likely to get rapid attension if I
make the wrong decision. ( I do plan on testing so I end up giving
the rapid attension)
