        Actually it was designed for a much weaker but non-trivial
        security model, and was laboriously upgraded to B2.
        There was some speculation at the time that it was more
        like B(1 7/8)...

        What was nice for a dumb user (me) is that mandatory
        access controls were almost invisible: I never knew that
        some things were protected from me: I couldn't see them!
