This is an important point, and I still don't think you have it exactly 
right.  When you say "including changes made by a reload", that really 
should say "ONLY IF the module has been reloaded".  Unless you reload 
it, the "mymod" that is in the module cache will never change, and 
therefore SomeFunc will always get the same version of myfunc().
