    Description

      This makes it possible to detect transient data inconsistency failures (e.g. related to timestamping differences between the primary and secondary of a replica set) that have been resolved by the time we've finished waiting for all operations to have replicated. This requires changing the "dbhash" command to call getMinimumVisibleSnapshot(), etc. as AutoGetCollectionForRead does currently.
