I wouldn't think so; but someone familiar with HOT logic could
probably determine whether the unmodified algorithm could be used by
reviewing the "simplifying assumptions" near the bottom of page 42,
and the page about "Generalizing to other database engines" (section
4.8). I think those portions might stand on their own without
reading the rest of the document.
