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.

 // Test that the SharedArrayBuffer memory is properly zeroed.

 function f() {

     var x = new SharedArrayBuffer(4096);

     var y = new Int32Array(x);

     assertEq(y[0], 0);

     assertEq(y[1], 0);

     assertEq(y[1023], 0);

 }

 if (typeof SharedArrayBuffer !== "undefined")

     f();
