      Right now in UpdateStage we perform a PlanStage::saveState before making changes and a PlanStage::restoreState afterwards. These operations can potentially be expensive and costly.

      We should investigate whether we can omit them in some cases. If not, then we should leave a comment explaining why we can't do that as it is not clear why they are needed.
