[issue17759] test_urllibnet.test_bad_address() fails on Ubuntu 13.04

[Barry A. Warsaw]

New submission from Barry A. Warsaw:

socket.gethostbyname('sadflkjsasf.i.nvali.d') gives a TimeoutError instead of an IOError on Ubuntu 13.04, causing the test to fail.

% ./python -m unittest test.test_urllibnet
.E../home/barry/projects/python/cpython/Lib/test/test_urllibnet.py:94: DeprecationWarning: FancyURLopener style of invoking requests is deprecated. Use newer urlopen functions/methods
  open_url = urllib.request.FancyURLopener().open(URL)
