    Description

      Some prerequisite knowledge is documented in SERVER-33159.

      Recover to a stable timestamp introduces a case, in crash recovery, where an `_mdb_catalog` collection document may exist without a corresponding WT table. SERVER-33159 describes how that can happen.

      SERVER-33159 is a short-term fix that accepts this state can exist. This ticket is to return the happens-before relationship between catalog entries and their on-disk WT tables, in the face of stable timestamp + logging changes for 4.0+ replica set members.

      This patch is for glue code to postpone performing the WT table drop until it is sure the collection drop has been persisted in a stable checkpoint.
