Two things I realized yesterday that need to be implemented (and some double-checking and/or opinion would be nice) while I wait for a full patch review.

One is ``python -v`` support. sys.flags has a verbose attribute that can be used to properly guard printing imported modules. It might be tricky, though, if sys.stderr is not set up properly during very early imports. I guess at worst I expose some sprintf() in imp just for this case (ugh).

Two is getting __import__() for situations where another import is triggered (e.g. fromlist stuff). I think the proper semantics is ``globals['__builtins__']['__import__'] if '__builtins__' in globals else  builtins.__import__``. Now where this gets tricky is that doing this means importlib.__import__(), when used directly from the importlib module, would sometimes use its implementation, and in other cases use builtins.__import__(). So either importlib.__import__() gets forked from builtins.__import__() so that it always uses importlib internally or simply don't worry about it and just have importlib.__import__() use builtins.__import__() when the need to trigger another import comes up. What do people think should happen?
