The fix (c910af2e3c98 + 53fc7f59c7bb) for this issue broke deletion of directories, which contain symlinks to directories.
(Directories with symlinks to regular files or symlinks to nonexistent files are unaffected.)

$ mkdir -p /tmp/a/b
$ ln -s b /tmp/a/c
$ python3.2 -c 'import shutil; shutil.rmtree("/tmp/a")'
$ mkdir -p /tmp/a/b
$ ln -s b /tmp/a/c
$ python3.3 -c 'import shutil; shutil.rmtree("/tmp/a")'
