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. check-in: d045f8b2d4 user: dan tags: sorter-coalesce-writes

Ensure that there is always at least one aReadMark slot usable by an unprivileged reader while a checkpoint is running. Also, if one or more transactions are recovered from a log file, initialize one of the aReadMark slots to contain mxFrame as part of the recovery process. check-in: e416359633 user: dan tags: trunk
