For your simple test dictionary, copy and deepcopy behaves 
identically. If you wish, you should test using values that are 
containers themselves.
With or without threads, modifying original (with the current 
contents) would never modify originalcopy neither originaldeepcopy, 
so you aren't testing anything here.
Try rewriting your test.
