Does not delete records from field tables when purge

Hello,

Please don't hack drupal node functions, records from field tables were not removed because of this hack:

                  /* copied from node_delete - to bypass node_access - cache_clear_all moved outside the loop */

                  db_delete('node')
                  ->condition('nid', $record->nid)
                  ->execute();

                  db_delete('node_revision')
                  ->condition('nid', $record->nid)
                  ->execute();
