Yes, the fact that the Austin Group is planning to require readdir to
be thread-safe and to mark readdir_r obsolescent. So effort put into
making readdir_r more usable, or worse yet, adding a readdir4, is a
waste of effort. Just make sure readdir_r is _safe_ against buffer
overflows from buggy FUSE modules, and advise application developers
to use readdir, not readdir_r.
