 Right now loaders (via load_module()) are responsible for certain
 boilerplate, import-related operations.  These are:
 
-1. perform some (module-related) validation;
-2. create the module object;
-3. set import-related attributes on the module;
-4. "register" the module to sys.modules;
-5. exec the module;
-6. clean up in the event of failure while loading the module.
