fix `gaierror: [Errno -9] Address family for hostname not supported`

error from unassociated interfaces.

related to facebook/tornado#593 - but the fix was only applied to 3.0

I've verified that this fix works for tornado 2.1, 2.4, 2.4.1, and the behavior it fixes does not trigger on tornado 3.0

closes #3045
