I was going to ask what if the created directory does not have permission 0777. But adjust_shared_perm follows immediately after, so we're good. It also answers the question why "mkdir(buffer, mode) && errno != EEXIST" should not be wrapped in xmkdir() or something to be used in other places as well.
