something that can wait, IMHO.

Yes, that's an option, too, and probably a good one. To go down that path,
we would drop the various "target" parameters and say loaders that need to
check for the reloading case should continue to provide load_module without
exec_module (at least for 3.4). runpy would use the rule that it supports
anything that exposes exec_module without create_module.
