    I've been given some help in this offline. Apparently, the bacula
    code is incorrectly using hosts_access. bacula should fork before it
    calls hosts_access because hosts_access will kill you on twist.
    Otherwise, you'll get either a deny or an allowed, and the thread
    continue from here.

    My offline helper was comparing the inetd source code. I can't find
    any reference in host_options(5) or host_access(3) which point to the
    correct usage.

    Is the FreeBSD documentation incomplete? Is there a more accurate
    documentation I can point the bacula developers to?

    FYI: The bacula approach is said to work under Linux and Solaris but
    I have yet to run my reproducible tests on those platforms.

    Thank you.
