-rw-r--r--

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.

 // 'this' is lexically scoped in arrow functions

 var obj = {

     f: function (expected) {

         assertEq(this, expected);

         return a => this;

     }

 };

 var g = obj.f(obj);

 assertEq(g(), obj);

 var obj2 = {f: obj.f};

 var g2 = obj2.f(obj2);

 assertEq(g2(), obj2);

 assertEq(g(), obj);
