+# The following tests work as follows:
+#
+#    1.0: Open connection [db1] and populate the database.
+#
+#    1.1: Using "PRAGMA writable_schema", destroy the database schema on
+#         disk. The schema is still in memory, so it is possible to keep
+#         using it, but any attempt to reload it from disk will fail.
+#
+#    1.3-4: Open connection db2. Check that it can see the db schema. Then
+#           close db1 and check that db2 still works. This shows that closing
+#           db1 did not reset the in-memory schema.
+#
+#    1.5-7: Similar to 1.3-4.
+#
+#    1.8: Close all database connections (deleting the in-memory schema).
+#         Then open a new connection and check that it cannot read the db.
