#                transaction left a very large non-hot journal file in the
#                file-system), then SQLite has to be careful that there is
#                not a journal-header left over from a previous transaction
#                immediately following the journal content just written.
#                If there is, and the process crashes so that the journal
#                becomes a hot-journal and must be rolled back by another
#                process, there is a danger that the other process may roll
#                back the aborted transaction, then continue copying data
#                from an older transaction from the remainder of the journal.
#                See the syncJournal() function for details.

# pager1-13.2.*: Same test as the previous. This time, throw an index into
