Yep.  I wasn't using the Samba code as my reference, however.  It's
presented as two 32-bit values in the SNIA doc (in two different places)
so I decided to work with it that way in the book.  I think that the
Leach/Naik draft also presents it that way.  I do point out that it should
be handled as a single 64-bit value.

Didn't know that.  When I get a chance I'll add an annotation to the
on-line version of the book.  Important detail.  Thanks!

PS. You never got back to me on the hybrid linked-list structure I
    proposed.  It's half written.  Any interest?
