+async/await in CPython code base
+''''''''''''''''''''''''''''''''
+
+There is no use of ``await`` names in CPython.
+
+``async`` is mostly used by asyncio. We are addressing this by
+renaming ``async()`` function to ``ensure_task()`` (see `asyncio`_
+section for details.)
+
+Another use of ``async`` keyword is in ``Lib/xml/dom/xmlbuilder.py``,
+class ``DocumentLS``. ``async`` property is not documented, not
+tested, and is not used anywhere. Methods that were likely supposed to
+work with it -- ``_set_async()`` and ``_get_async()`` -- are not used
+anywhere either. These methods will be deprecated in 3.5 and removed
+in 3.6.
