I'm not familiar enough with the current state of Aura and Ash to review this.

Mike, can you take a look?

[msw, 2014-10-23 20:56:13]

I guess if this isn't using any ash-specific code, and the desktop host doesn't
actually matter, then this is probably fine. rubber stamp lgtm.

I should have given more context. Desktop Chrome for Linux and Windows uses Ash.
I am changing ChromeOS Athena to no longer compile Ash. There are a lot of
things that Athena should not compile but does. Ash is one of these things.
