It's an interesting point; I personally don't see much value in coverage 
of less than 100%, if you're going to look at coverage: no-one is going 
to focus on or potentially even notice whether coverage moved from 99% 
to 99% (no typo), even though a bunch of new uncovered code may have 
been introduced.

If people are actually using these blocks, then so be it, but it feels 
like the people who want them to stick around are saying they're using 
them just on the off chance they might use them, which feels like a poor 
reason to keep a bunch of dead code around.

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