 // Classes for managing the SafeBrowsing interstitial pages.
 //
 // When a user is about to visit a page the SafeBrowsing system has deemed to
 // be malicious, either as malware or a phishing page, we show an interstitial
 // page with some options (go back, continue) to give the user a chance to avoid
 // the harmful page.
 //
 // The SafeBrowsingBlockingPage is created by the SafeBrowsingService on the UI
 // thread when we've determined that a page is malicious. The operation of the
 // blocking page occurs on the UI thread, where it waits for the user to make a
 // decision about what to do: either go back or continue on.
 //
 // The blocking page forwards the result of the user's choice back to the
 // SafeBrowsingService so that we can cancel the request for the new page, or
 // or allow it to continue.
 //
 // A web page may contain several resources flagged as malware/phishing.  This
 // results into more than one interstitial being shown.  On the first unsafe
 // resource received we show an interstitial.  Any subsequent unsafe resource
 // notifications while the first interstitial is showing is queued.  If the user
 // decides to proceed in the first interstitial, we display all queued unsafe
 // resources in a new interstitial.
