That variable does indeed seem to not be used, and hasn't been used since it
was committed in d168b666823. The question is if it's a left-over from
development which can be removed, or if it should be set and we're missing an
optimization. Having not read the referenced paper I can't tell so adding
Peter Geoghegan who wrote this for clarification.
