I don't think you're using this in this CL. Did it belong in a different one?

Actually, I'm not using anything in this CL yet :)

This file was kind of the odd one out and I couldn't decide which patch to put
it in when I was splitting up this huge one:
http://codereview.chromium.org/10572040. I chose this patch because this is what
allows the hosts to be hooked up. Anyway, you can treat this file's change as a
somewhat separate thing.
