// When those two steps have completed, we're past the situation that would
// trigger a fatal assertion when the object document gets cycle-collected.
// So at that point we remove our iframe, and (after a rAF tick) trigger a
// GC and CC, and then consider the test as having passed if we're still
// alive at that point.
