Failure with 3.4.0c1:

[170/394/5] test_importlib
test test_importlib failed -- Traceback (most recent call last):
  File "C:\Programs\Python34.32\lib\unittest\case.py", line 57, in testPartExecutor

    raise exception
ImportError: Failed to import test module: test.test_importlib.source.test_abc_loader

    module = self._get_module_from_name(name)

    class PyLoaderMock(abc.PyLoader):
AttributeError: 'module' object has no attribute 'PyLoader'

On the other hand, the test passes on a fresh debug build.
