Why do we need to specify an opener here? This wouldn't change from the initial
provisional load, right? 

[Shishir, 2011/05/12 22:05:18]

Yes that is correct. But suppose that the initial load did not hit a prerendered
page, but the redirect url did. Essentially anytime we might end up using a
prerendered page, we need to inspect the opener property.

                     GURL /* last url */,
                     GURL /* url redirected to */)
