I'm not, but I sure hope someone is -- we could *really* use this in
the SSI patch.  With something providing the equivalent
functionality to Andres's previous patch, and about one day's work
in the SSI patch, SSI could guarantee that an immediate retry of a
transaction rolled back with a serialization failure would not fail
again on conflicts with the same transaction(s).  This would be a
very nice guarantee to be able to make.
