auto final callback gets called too many times in case of exception

[ARAtlas]

If an exception is thrown in the final callback of an auto, the final callback ends up being called multiple times. In this example, "This should only run once" will be logged twice.

async.auto({
  func1: function(callback) {
    callback(null);
  },

  func2: ['func1',
    function(callback) {
      callback(null);
    }
  ]

},

  // Final callback. This should only run once...
  function(err) {
    console.log("***** This should only run once *****"); //...but somehow this is called twice
    throw new Error("Something goes wrong");
  }
);

Any thoughts on integrating the above fix? An alternative way to fix it would be to wrap the final callback in a process.nextTick:

process.nextTick(function() {
  callback(null, results);
});
