Change the Owner of a Running Process

[Roger Oberholtzer]

If the app belongs to root (chown root 'app'), then setting the SUID
bit (chmod +s 'app') should result in the program running as root and
not whoever mozilla is running as. Or whoever the app file belongs to.

However, do heed the warnings below. I would never do this with
an app I got somewhere. There are few cases where this is needed.

If you just want to control app files so they do not belong to the
user running mozilla, consider using the 'guest' account or some other
non-privleged account. Do the same two commands listed above, replacing
root with guest.
