Changes to src/pager.c.

    14     14   ** The pager is used to access a database disk file.  It implements
    15     15   ** atomic commit and rollback through the use of a journal file that
    16     16   ** is separate from the database file.  The pager also implements file
    17     17   ** locking to prevent two processes from writing the same database
    18     18   ** file simultaneously, or one process from reading the database while
    19     19   ** another is writing.
