 * makes parts of the API of Maintenance that is hidden by protected visibily
 * visible for testing, and makes up for a stream closing hack in Maintenance.php.

 * This class is solely used for being able to test Maintenance right now
 * without having to apply major refactorings to fix some design issues in
 * Maintenance.php. Before adding more functions here, please consider whether
 * this approach is correct, or a refactoring Maintenance to separate concers
 * is more appropriate.
 *
 * Upon refactoring, keep in mind that besides the maintenance scrits themselves
 * and tests right here, also at least Extension:Maintenance make use of
 * Maintenance.
 *
 * Due to a hack in Maintenance.php using register_shutdown_function, be sure to
 * finally call simulateShutdown on MaintenanceFixup instance before a test
