I understand 4MB might be too small, but isn't 256MB a bit too much? Let's use
something that is a margin on top of the biggest message we've seen. I'd be more
comfortable with 32 or 64 to start with.

   mojo::embedder::Init(scoped_ptr<mojo::embedder::PlatformSupport>(
       new mojo::embedder::SimplePlatformSupport()));
 }
