      Description

      The new DataLoaderServlet has an incorrect pattern for obtaining a connection, writing on the namespace, and managing the commit() / abort() decision. As a result, if a client http connection is terminated abruptly then the data loader fails to clean up the write set and the clients data will make it into the next commit. This causes an inconsistency between the B+Tree indices and the RWStore and can render the namespace unusable.
