| 19:28 | Merge the sorter-coalesce-writes branch into the trunk. This improves CREATE INDEX performance on some platforms. (check-in: e1e9cb08b0 user: dan tags: trunk) | |

| 18:50 | When reusing pages as part of creating a new index, allocate the leaves from each free-list trunk page in ascending order, instead of trying to maximize localization for each individual allocation. This increases the chance that pages will be written to disk in ascending order by a large CREATE INDEX statement, improving overall performance.
