A background process *is* a child of the shell that spawned it, and
anything it sends to stdout or stderr will appear in that shell.

Not always the case from what I've seen. Had a problem with gphoto2
a while ago - I use a card reader now because of it - and _no_ error
messages appeared *anywhere* I searched to indicate why the application
crashed when trying to access the camera. Plus, on Debian Etch,
gnomesword 2.1.9-1 crashes without any output messages either to console
or .xsession-errors when executed without or without an ampersand.

Start it in xterm/konsole/rxvt/whatever and see. Alternatively, start it
with "strace whatever".
