Putting a "just get the one that's already there" loader at the front
should take care of this.
Having __import__ always generate the module would make it harder to
use things that aren't really modules. (examples: A module with a
custom __dict__ type that gripes at external modification; the
forwarders used when a module changes its name; Lazy Importers)
