OTOH, ensuring that if any exception is thrown when importing a module, it will not appear in sys.modules (and the exception is raised each time you try to import) is IMO a very useful property, and I think would solve what I think is Jim's issue at the root.
It's going to be difficult to ensure that nothing ever gets a reference to a broken module, because of circular imports. Suppose A imports B, which imports A. If A's initialisation subsequently fails, then even if A is removed from sys.modules, B still contains a reference to the broken A.
