I'm not sure I understand how triggering via unittest or via unittest 
(no typo, both these __main__ blocks and python -m unittest are using 
the same test runner) could make a difference.

And sorry, to be clear, I'm only taking about the ones in 
unittest/mock/testmock - Rob Collins confirmed these where never needed 
in a private reply:
