+# autovacuum-2.2.*: Create some tables. Ensure that data pages can be
+#                   moved correctly to make space for new root-pages.
+# autovacuum-2.3.*: Drop one of the tables just created (not the last one),

+#                   the free root-page location.

+#                   root-page it requires is on the free-list.
+# autovacuum-2.5.*: Check that a table with indices can be dropped. This

+#                   indices/table btrees could move the root-page of another.
+#                   The code-generation layer of SQLite overcomes this problem
