[restart] is implemented like this:
restart(app) {
if (! app)
exec(argv[0]); // exec ourself
exec(app); // exec something else
}
so just the restart tag causes blackbox to run itself again. It never really
exits, it just calls exec() in its own process. If (tag) is specified that tag
is used as the process to exec.
[exit] just closes everything down and exit()s.
