PyImport_ExecCodeModuleEx(): remove module from sys.modules in error cases. PyImport_ReloadModule(): restore the module to sys.modules in error cases. load_package(): semantic-neutral refactoring from an earlier stab at this patch; giving it a common error exit made the code easier to follow, so retaining that part. _RemoveModule(): new little utility to delete a key from sys.modules.
