OK.  I don't think Octave should close sdterr and stdout (or even
stdin) just because you are running in the background.  Most likely it
is just a shell/terminal settings issue that you can easily work
around, so unless someone can point to an actual bug in Octave, I
don't see anything that needs to be fixed.
