; that is, applications where the database
            grows and shrinks repeatedly. For example, because Berkeley DB does
            page-level locking, the maximum level of concurrency in a database
            of two pages is far smaller than that in a database of 100 pages, so
            a database that has shrunk to a minimal size can cause severe
            deadlocking when a new cycle of data insertion begins.
