It shouldn't actually sit there forever. Just for a very long time.

Well, something obviously went wrong. There's no point for the test
to keep trying to remove a parent when it can't remove the child, so
we might as well give up in that case.
I installed the following patch into gnulib. Thanks for reporting it.

* m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Don't bother to
try to remove a parent directory if the child couldn't be removed
(except for the first rmdir, which could fail because the child
doesn't exist). Problem reported by Jeff Blaine in
<http://lists.gnu.org/archive/html/bug-tar/2007-03/msg00014.html>.
