What about Python code that modifies that module __dict__ directly?  For
example, using vars() or globals() to get a reference to it and doing
__setitem__ on it.  My warning code only catches assignments that go
through the module tp_setattro slot.  I suppose warning about direct
__dict__ poking would require a proxy object to wrap the module dict.
