The nameserver responsible of sha2.hboeck.de is down and this hostname is used in test_ssl. The result is that all trunk buildbots are red (error).

support.transient_internet() should catch socket.gaierror.

One example: http://www.python.org/dev/buildbot/all/builders/amd64%20gentoo%20trunk/builds/1007

Traceback (most recent call last):
  File ".../Lib/test/test_ssl.py", line 261, in test_algorithms
    s.connect(remote)
  ...
gaierror: [Errno -2] Name or service not known

Patch to catch gaierror(EAI_NODATA) and gaierror(EAI_NONAME).

Looks ok to me.

I commited the patch as r81571 in trunk. Wait for the buildbot before porting it to other branches.

There is another error:

test test_ssl failed -- Traceback (most recent call last):
  File "/scratch/pybot-buildarea/trunk.klose-ubuntu-i386/build/Lib/test/test_ssl.py", line 261, in test_algorithms

    return getattr(self._sock,name)(*args)
error: [Errno 110] Connection timed out

transient_internet() should also catch socket.error(errno.ETIMEDOUT).

Apparently it's ok.
