each fts state is entirely in the fts_open() handle
to be thread-safe all or all but one caller must use FTS_NOCHDIR

if the system imposes a PATH_MAX limit then FTS_NOCHDIR will
limit search pathname depth to PATH_MAX

FTS_NOCHDIR limitations could be handled by opendirat()
but the ast fts implementation does not iffe for opendirat() yet
