Reach 100% coverage

It's a nice plan, but TBH I'm not sure how to go about testing coroutines, asyncio connections and yield from statements. Currently, that's the only bit that's not covered.

... of course, code coverage doesn't prove the code does the right thing, but at least is shows it does something ;)

bottom's tests look as though they could be good inspiration.

This article on "Testing, async, asyncio, and performance" also bears reading.

Looks very interesting :) (It looks like there's a typo in the link, it resolves to a github page)
