We check if sending a resize succeeded but not here. Should we return false if
Send fails or do we just let it immediately go into the 'he's dead Jim' state?

[piman, 2014/10/31 20:35:52]

Sure, we can. Note that since it's an async message, Send basically won't fail
unless we fail to initialize the RenderProcessHost (and in that case, I don't
think we even get here). But it doesn't hurt to be defensive.

Done.
