+       * NEWS: Fix some race conditions with tar -x --same-owner.
+       * src/extract.c (ARCHIVED_PERMSTATS): Add a comment saying that
+       S_IRWXG | S_IRWXO might be masked out.
+       (set_mode): Set the mode if some bits were masked out originally.
+       (set_stat): Don't chmod before chown, as that might temporarily
+       grant permissions that we don't want to grant.  The chmod was
+       there only to work around broken hosts, so add a comment advising
+       users not to use those broken hosts instead.
+       (repair_delayed_set_stat, extract_dir):
+       Remember to mask out current umask before inverting permissions.
+       (extract_dir): If the owner might change, or if the mode has
+       special bits, create the directory 700 at first, but restore it later.
+       (open_output_file): New arg mode; all uses changed.
+       (extract_file, extract_node, extract_fifo): If the owner might
+       change, omit group and other bits at first, but restore them after
+       changing the owner.
