Out of curiosity, what exactly is the purpose of the goto in the
above code? Since we set module_loaded_flag just prior to it, the
first if statement must fail after the goto, so we just fall down
to where we would have been without the goto.

It all looks a tad pointless to me...

Best wishes from Riley.
