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.
1 // Bug 717104 - Unreachable debuggee globals should not keep their debuggers
2 // alive. The loop is to defeat conservative stack scanning; if the same stack
3 // locations are used each time through the loop, at least three of the
4 // debuggers should be collected.
6 for (var i = 0; i < 4; i++) {
7 var g = newGlobal();
8 var dbg = new Debugger(g);
9 dbg.onDebuggerStatement = function () { throw "FAIL"; };
10 dbg.o = makeFinalizeObserver();
11 dbg.loop = g; // make a cycle of strong references with dbg and g
12 }
14 gc();
15 assertEq(finalizeCount() > 0, true);
