Patch LGTM.
I'm getting 4 additional failures on 3.4: test_asyncio test_contextlib test_email test_statistics

* test_statistics is fixed by the attached patch.
* test_email fails in Lib/email/_policybase.py:95 -- this probably deservers a separate issue.
* test_contextlib fails in Lib/test/test_contextlib.py:107 even though these tests are decorated with @support.requires_docstrings (defined in Lib/test/support/__init__.py:1716).  Even with -00 the _check_docstrings function seems to have a docstring (the exact line I used to run the tests is "./python -OO -m test -v test_contextlib").
* test_asyncio has lot of failures, and most of them look like:
  ======================================================================
  ERROR: test_call_later (test.test_asyncio.test_events.PollEventLoopTests)
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "/home/wolf/dev/py/py3k/Lib/test/test_asyncio/test_events.py", line 1315, in setUp
      super().setUp()
    File "/home/wolf/dev/py/py3k/Lib/test/test_asyncio/test_events.py", line 188, in setUp

      get_event_loop_policy().set_event_loop(loop)
  AttributeError: 'object' object has no attribute 'set_event_loop'
Without -OO test_asyncio works fine.  I haven't investigated this further.
