Nit: Can you line up the comments (and set them at least two spaces apart from
the code)?

[Mike West, 2012/06/01 13:35:17]

Done.

[Bernhard Bauer, 2012/06/01 13:59:35]

O RLY? ;-)

It was done in my head.

Now it's done in code. SRSLY.

   // in ChildProcessSecurityPolicy, but excluding schemes like
   // `chrome-extension`.
