OK, pushed to the website[1] and unicorn.git as
commit 3318b070c6513a3baa7ce7ac26f4835f46ccff1f

    examples: add run_once to before_fork hook example

    There may be code in a before_fork hook which should run only once,
    document an example using a guard variable since it may not be
    immediately obvious to all users.
