+1 to everything Russell just said and of course Blueprints for this. One for #3 (changing from mox -> Mock) would be good so that anyone who is bored or finds this urgent can collaborate. Also, we need to make sure reviewers are aware (Hopefully they are reading this).

That's fine with me if everyone feels that way.  I'm afraid it's not a
quick move because of how much we're using mox.  A practical approach
would probably be:

1) Prefer mock for new tests.

2) Use suggestion #2 above to mitigate the Python 3 concern.

3) Convert tests to mock over time, opportunistically, as tests are
being updated anyway.  (Or if someone *really* wants to take this on as
a project ...)
