    Exit with status 0 from kadmind
    
    Typically, 0 denotes successful exit.  In particular, init systems
    will complain if another different value is returned.  This presents a
    problem for automated installation jobs which want to restart kadmind.
    
    `service kadmin stop` typically sends SIGTERM, which is caught by
    verto and passed to our handler.  Besides cleanup, we then call
    verto_break(), which causes the verto_run() event loop to return.  The
    weird return code has been present since the addition of the kadmin
    code, which used a similar event model for signals.
