 * @param {number} limit - The maximum number of async operations at a time.
 * @param {Function} iteratee - A function to apply to each
 * item in `coll`. The `key` is the item's key, or index in the case of an
 * array. The iteratee is passed a `callback(err)` which must be called once it
 * has completed. If no error has occurred, the callback should be run without
 * arguments or with an explicit `null` argument. Invoked with
 * (item, key, callback).
 * @param {Function} [callback] - A callback which is called when all
 * `iteratee` functions have finished, or an error occurs. Invoked with (err).
