    Description

      Waiting for the drop command gets replicated to a majority doesn't guarantee the drop completes on the primary, so after the command returns, the drop-pending collection reaper will actually drop the collection, which takes the database lock in X mode. The asynchronous DB lock in X mode may be unexpected to users, especially transaction users, because it will block (or abort when SERVER-33244 is done) transactions waiting for the DB lock.
