	I admit ignorance as well... when I see a "disowned" job on an ITS, its
	usually associated with some username somewhere.

	Ignorant question for today...
	What's the difference between running a job in the background and
	disowning it?

    beyond my limited technical ability to describe. someone on this list should
    be able to help you more.

Roughly speaking, a disowned job has no superior nor controlling TTY,
(f'rinstance like COMSAT normally runs).  DDT lets you run jobs in
background, (e.g.  w/ or ) by running them without the TTY and
handling output differently.  Their superior is still DDT.  From ITS's
point of view the only difference between running a job in foreground or
in background is who owns the TTY.

For a more detailed description, do :UUO .DISOWN, .ATTY, etc.


PS: bug-its people: what do you think of using BUG-ITS for questions
    like this?  I think it's a good idea, but if it's going to cause the
    fixers of bugs to remove themselves on the grounds of traffic
    levels, then we should have yet another list.
