+1 to first: Aborts aren't particularly frequent actions, but having
them return faster makes sense if you have a session pool and people are
waiting to run another transaction.

-1 to second: If there are any temporary deleted files then it is
because we've done a large sort, hash join etc, so avoiding the sync
makes no difference to the overall response time.
