[issue6563] inserting None into sys.modules does not raise ImportError with importlib

[Brett Cannon]

New submission from Brett Cannon <brett at python.org>:

When you insert None into sys.modules, the built-in import raises an 
ImportError, but importlib does not.

See http://mail.python.org/pipermail/python-dev/2009-July/090780.html for 
the discussion that brought this up.
