          Description

          Eviction currently doesn't aggressively select internal pages that have been emptied (that is, oplog internal pages). Those pages are marked WT_READGEN_OLDEST, so can be easily identified.

              This one has been merged into develop, but I mis-titled it so the GitHub merge wasn't reflected into the JIRA ticket; see the GitHub link for more information.
