    Description

      On clean shutdown when in FCV 3.6 a 4.0 binary must:

      • Set the WT "recovery timestamp" to 0
      • Take an unstable checkpoint
      • Enable WT logging for all tables

      Additionally, a 4.0 binary running in FCV 3.6 should persist some state such that a 3.6 binary cannot startup on the datafiles following a crash.
