New submission from Gregory P. Smith <greg at krypto.org>:

test_404 (test.test_xmlrpc.SimpleServerTestCase) ... Exception in thread Thread-1:
Traceback (most recent call last):
  File "/home/greg/oss/cpython/Lib/threading.py", line 938, in _bootstrap_inner

    self.socket.bind(self.server_address)
OSError: [Errno 99] Cannot assign requested address

I'm preparing an IPv6-only buildbot.  There is no IPv4 localhost.
