I assume you mean that the extension module would be able to clearly signal that it can't be reloaded, right? I agree that that's helpful. If you're wrapping a C library, then the way that library is implemented might simply force you to prevent any attempts at reloading the wrapper module. But if reloading is possible at all, it would be even more helpful if we could make it really easy to properly support it.

When loader.exec_module() gets called, it should raise ImportError if the module does not support reloading.
