What happens is that atomic_write on Python 2.7 on Windows will try to convert the paths to unicode, but this triggers the import of the encoding module for the file system codec, which in turn triggers the rewrite, which in turn again tries to import the module, and so on. This short-circuits the cases where we try to import another file when writing a pyc file; I don't expect this to affect anything because the only modules that could be affected are those imported by atomic_writes. Fix #3506

The ``pytest`` framework makes it easy to write small tests, yet
scales to support complex functional testing for applications and libraries.
An example of a simple test:
.. code-block:: python
# content of test_sample.py
def inc(x):
return x + 1
def test_answer():
assert inc(3) == 5
To execute it::
$ pytest
============================= test session starts =============================
collected 1 items
test_sample.py F
================================== FAILURES ===================================
_________________________________ test_answer _________________________________
def test_answer():
> assert inc(3) == 5
E assert 4 == 5
E + where 4 = inc(3)
test_sample.py:5: AssertionError
========================== 1 failed in 0.04 seconds ===========================
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <http://docs.pytest.org/en/latest/getting-started.html#our-first-test-run>`_ for more examples.
