When a socket connection is refused, it isn't a failure
of the test, it could just be network issues or the
site that we are trying to connect to (we really need
to point all tests to python.org but I don't know if we
has SSL set up).

The attached patch catches socket.error and checks if
it is because of a connection refusal (based on its
errno).  If that is the case, the test to returns,
otherwise the exception is re-raised.
