Release a page. If the number of references to the page drop to zero, then the page is added to the LRU list. When all references to all pages are released, a rollback occurs and the lock on the database is removed. @throws SqlJetException

            } catch (SqlJetException e) {

            /* Increment the value just read and write it back to byte 24. */
