There are lots of ways to do this; on our systems we run lisp on a
separate tty (using /etc/inittab) - this has the added benefit of
having /sbin/init restarting it if it dies/is killed.

You could also run lisp under GNU screen, which would allow you to
connect to it and see the repl if there were any errors.

Another option is you could run hunchentoot directly instead of
creating a thread for it. If you looked at server.lisp you could
figure out how this is done just by looking at start-server.

Another option is you could run the sbcl function (sb-ext:process-wait
(hunchentoot::server-listener s))

I recommend keeping the repl around; we had a number of problems when
we deployed that were fixed "in the field" by connecting to the repl
and patching our app while it was running.
