Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 var o = {y: function() {}};

 var a = [o, o, o, o, o, o, o, o, o];

 Number.prototype.y = 0;

 a[7] = 0;

 try {

     for (var i = 0; i < 9; i++)

         a[i].y();

 } catch (exc) {

     assertEq(exc.name, "TypeError"); // should happen when i == 7

 }
