nit: What's going on with those two separate groups of headers? That seems to be
against the style guide.

[Mike West, 2011/05/24 16:53:51]

Correct.  It's an artifact of how I built the file, and I'm killing it now.

Done.

Avoid NOTREACHED() in tests: only works in Debug mode, and causes a "crash". Did
you mean ADD_FAILURE?

[Mike West, 2011/05/24 16:53:51]

I apparently did.
