IMO the background process should be an usual daemon:
http://www.steve.org.uk/Reference/Unix/faq_2.html#SEC16
(you may even use something like start-stop-daemon on debian
bases systems)

If you need a restart control (e.g. if the process die),
considering a very simple daemon that starts the working
process as a direct child, wait() on them and restart it
whenever it returns. This controlling process may even
provide a socket/named pipe interface to control.
