      movePrimary may fail on the clone phase with error 7118501 when $out is executed at the same time.

       

      The sequence of events to end up with the mentioned error is:

      1. $out operation starts
      2. the temporal collection for $out is created
      3. movePrimary starts
      4. movePrimary starts the clone phase
      5. $out operation fails with a MovePrimaryInProgress error
      6. the temporal collection is dropped here
      7. movePrimary finishes the clone phase
      8. movePrimary fails here because cloned collections don't match with the expected collections to clone
