Currently reload() returns the module that loader.load_module() returns, rather than returning the one in sys.modules.  This is different from what happens during normal import.  I would expect reload() to return what's in sys.modules.  Perhaps this got overlooked when we moved reload()?  I haven't had a chance to verify, but I do recall that the switch to importlib-based import in 3.3 exposed a bug where importlib wasn't returning the module in sys.modules during normal import.
