No problem.  That's how ideas are explored and improved.  The brick
wall was that there seemed to be overwhelming opposition to any new
technique which causes serialization failures under conditions where
the cause isn't blindingly obvious, regardless of the resulting
improvements in data reliability.

Well, that's certainly not the novel part -- those techniques were
described and proven theoretically decades ago and have been in use
by many popular products for almost as long.  It's that non-blocking
SIREAD lock which is the fun part.  ;-)
I just wish I had time to read all the documents referenced in the
