+ * @param {number} limit - The maximum number of async operations at a time.
+ * @param {AsyncFunction} iteratee - A function to apply to each item in `coll`,
+ * which should use an array as its result. Invoked with (item, callback).
+ * @param {Function} [callback(err)] - A callback which is called after all the
+ * `iteratee` functions have finished, or an error occurs. Results is an array
+ * containing the concatenated results of the `iteratee` function. Invoked with
