In Python 2.1.3 trying to open a URL that does point 
to a non-existing domain with urlopen from urllib2 will 
raise a

urllib2.URLError: <urlopen error host not found>

That's what I'd expect Python 2.2.2 to do, too. But 
with Python 2.2.2 I get a

socket.gaierror: (-2, 'Name or service not known')

Error instead. I think this is a bug because

a) one would not expect urlopen to raise errors other 
than HTTPError and URLError (from what the docs say)

b) it breaks code that relies on the error behaviour of 
Python 2.1.3

Cheers

Joachim
