My expectation is that if `module->nm.module_start_func` is used, it probably means `smoption.attribute` should be ignored.

Actually, there are games where both are specified:

I'm not sure what's correct here (ought to create tests), but it leads me to believe that the `module_start_thread_stacksize` etc. are all related to the module_start_func` parameter.
