| /*Fix this code! The callback should be called with all the users loaded. | |
| The order of the users should match the order of supplied user ids. Because this | |
| function is asynchronous, we do not care about its return value. | |
| # Arguments | |
| * userIds: an Array of numeric user ids. | |
| * load: a Function used to load user objects. Expects a numeric id and a callback. | |
| * The callback will be called with the result of loading the user with the specified id | |
| * (either a user object or null). | |
| * done: a Function that expects an Array of user objects (as retrieved from `load`). |
