It *is* possible to have a directory on the orphan list, since it is possible
to have an open-unlinked directory if one cd's into the directory before it is
unlinked (note nlink = 0, dtime is an inode number, not time):
$ mkdir foo
$ cd foo
$ rmdir ../foo
$ ls -lid .
289432 drwxrwxr-x 0 mythtv mythtv 0 Nov 7 13:23 .
