I have a blog post planned, but not yet started, describing what I found
worked and didn't.  The tl;dr verison is something like:

- - Convert doctests to Sphinx docs.

- - Get to 100% statement coverage with good assertions.

- - Add fully-covered pure-Python reference implementations for any
  C extensions, and ensure that they pass *all* the same tests.

- - Follow the "straddle" pattern outlined by Lennart Regebro:
