Last change on this file since 1318 was 1318, checked in by Gregg Young, 17 years ago

Fix dbl free error for deletes by disabling fSyncUpdates for deletes; ironically the container now update faster then with it on. Also improved failure of container to update following an archive extract. It now should work for all but may be the largest archives (based on root filenames). It work with the largest I could find.
