 * This test does not use glodaTestHelper because:
 * 1) We need to do things as part of the test without gloda having remotely
 *    thought about opening the database.
 * 2) We expect and desire that the logger produce a warning and glodaTestHelper
 *    takes the view that warnings = death.
 *
 * We do use the rest of the test infrastructure though.
