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.

 // onPop handlers fire even on frames that make tail calls.

 var g = newGlobal();

 var dbg = new Debugger(g);

 var log;

 g.eval('function f(n) { if (n > 0) f(n-1); else debugger; }');

 dbg.onEnterFrame = function handleEnter(frame) {

     log += '(';

     frame.onPop = function handlePop(c) {

         log += ')';

         assertEq(typeof c == "object" && 'return' in c, true);

     };

 };

 log = '';

 g.f(10);

 assertEq(log, "((((((((((()))))))))))");
