      Description

      Related and found whilst investigating HPCC-18495.
      Probably a very long standing bug, it is also likely to be quite rare.
      The problem can happen if whilst a workunit is being created and before it has commit new nodes, a read or workunit scan of the newly created workunit starts and in doing so initializes the workunit with blank nodes.
      The create will then also add those same nodes and anything reading it will hit ambiguity errors.

      Fix = reading/scanning a workunit should not be creating and commiting changes at all.
