+#   1. Create a large database.
+#   2. Set the pager cache to be very small.
+#   3. Open a transaction. 
+#   4. Run the following 100 times:

+#      b. Copy all files on disk to a new db location, including the journal.
+#      c. Verify that the new db can be opened and that the content matches
+#         the database created in step 1 (proving the journal was rolled
