Doctrine 2 - Retrieving the lastest record from history table

Using a status_history table that will save the date and time a status was modified for a particular record in entries, I'm trying to find the easiest way to also get the current status, AKA, the status with the lastest date.

For instance consider the following: status_history

+----+----------+------------+-----------+
| id | entry_id |   status   | timestamp |
+----+----------+------------+-----------+
|  1 |        1 | Processing | 15:05:09  |
|  2 |        1 | In Review  | 15:05:18  |
|  3 |        1 | Complete   | 15:05:26  |
+----+----------+------------+-----------+

And of course, our entry: entries

+----+--------+
| id | title  |
+----+--------+
|  1 | Foobar |
+----+--------+

How can I retrieve, with DQL, the the latest status (technically the current status) for a particular entry, without having to maintain a latest_status_id column in my Entry entity?

Consider the call $entry->getCurrentStatus() would return "Complete". However, in the case we have a great amount of status records for that entry, a second query to load all statuses might turn into a performance drop.

NOTE: In this article they describe it with the extra column approach, using a locking mechanism for concurrency. I'd like to avoid this approach unless this is the correct one, since we're trying not to have double relations for each table (status_history.entry_id and entry.latest_history_id).
