A browser functionality fill-in I ended up writing and sharing on http://stackoverflow.com/questions/3141064/how-to-stop-all-timeouts-and-intervals-using-javascript to batch cancel javascript's basic deferred execution functions.

cancelAll.js

(function(deferFunctions) {
  for (var setter in deferFunctions) (function(setter, clearer) {
    var ids = [];
    var startFn = window[setter];
    var clearFn = window[clearer];

    function clear(id) {
      var index = ids.indexOf(id);
      if (index !== -1) ids.splice(index, 1);
      return clearFn.apply(window, arguments);
    }
    function set() {
      var id = startFn.apply(window, arguments);
      ids.push(id);
      return id;
    }
    set.clearAll = function() { ids.slice(0).forEach(clear); };

    if (startFn && clearFn) {
      window[setter] = set;
      window[clearer] = clear;
    }
  })(setter, deferFunctions[setter]);
})(
{ setTimeout: 'clearTimeout'
, setInterval: 'clearInterval'
, requestAnimationFrame: 'cancelAnimationFrame'
});

// Some example timers of all types:
requestAnimationFrame(console.error);
setInterval(console.info, 1000, 'interval');
setTimeout(alert, 0, 'timeout');

// Now you can clear all deferred functions
// by execution type, whenever you want to:
window.setTimeout.clearAll();
window.setInterval.clearAll();
window.requestAnimationFrame.clearAll();
