Actually, there should no longer be a need to use contextlib.nested.
We've explicitly dropped Python 2.6 compatibility, which means we're
expecting compatibility with Python 2.7+ only, and as of Python 2.7, the
'with' statement supports accepting multiple 'as' clauses.  The
contextlib.nested tool was really only necessary to work around that
functionality being missing in Python 2.6, and has been deprecated as of
Python 2.7 because it's no longer necessary.
