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.

The sqlite3_close() interface returns SQLITE_OK even if there are outstanding
...
sqlite3_stmt and sqlite3_backup objects. The connection becomes a zombie.
Resource deallocation is deferred until the last sqlite3_stmt or
sqlite3_backup object closes. This is intended to help SQLite play nicer
with garbage collectors.
