Change needed for tests to pass, but should be reverted in #38.
This one's related to #38. It turns out that while trying to mock a context manager kind of works, it will do the wrong thing in edge cases like when an exception is thrown from inside a `with` block, silently swallowing it and causing a return that's completely wrong. There may be some way to fix the mock to make it do the right thing, but instead of getting fancier with these mocks that are already awful, instead repair the problem by defining a plain class that implements context manager and just use that.
