i wonder if we should make the page runner manage this entire loop. Where,
effeictively, we say page_runner.Run(possible_browser) and make callers of this
pass in a possible_browser instead. That way page_runner can customize the
startup options of the browser and (if needed) tear it down during replay as
needed.

Done.
