Rick,

Yes, the job control provided by Gnome 3's session manager seems to be
doing a better job than Gnome 2's did.  I've tried starting my script
from various locations and then logging out and back in.  I don't seem
to have the issue with orphan processes that I did before.

That said, at the same time I have also mostly rewritten the script
and this may account for it behaving better, too.  Before it was a
collection of about ten files or so.  Now, I've rewritten it to have
most of those external scripts be shell functions.  I also
consolidated the various versions of the script into one, controllable
from a settings file.  With fewer processes spawned, there are fewer
that can be left behind.

Also, the forum link you provided showed how to use a lock file
properly from within a script to control multiple executions.  This is
a better solution than just running killall, so I'm using that now.
Thanks.

Again, it's still not a general solution, but it is definitely working
well enough for now.  Add to that the story about Gnome Shell
Extensions recently seen on Slashdot, and now I have Gnome 3 behaving
much more closely to how I would like it (meaning I can put off
switching desktop environments for the time being).
