[Bug 1154599] Re: getaddrinfo() returns -11 (EAI_SYSTEM) instead of -2

[Adam Conrad]

Colour me confused, but this seems to be behaving exactly as the manpage
suggests it can.  Where is the actual bug in eglibc here?  It seems
monumentally unclever for python to raise a different exception type
depending on how gai() returns, which seems to be what's causing the
headache here.

      except socket.gaierror as error:

  $ dpkg-query --show python2.7-minimal

  This is a behavioral change from quantal (2.7.3-5ubuntu4).
