All right, that's good to know, but I'm probably not communicating the
level of my confusion very well here :-). I have NO IDEA what the
exec() call should contain (and thus, no idea which one is "the most

I don't want to "execute a new program". I just want to daemonize the
one that's running.
So ultimately the question is: how should the forking code in the
recipe be modified, so that it satisfies the requirements of OS X?
What does an actual, concrete exec() call look like in this case, and
at what point in the code should it occur?
