-/**
- * A stub cache implementation to be used during the installation process.
- *
- * The stub implementation is needed when database access is not yet available.
- * Because Drupal's caching system never requires that cached data be present,
- * these stub functions can short-circuit the process and sidestep the need for
- * any persistent storage. Obviously, using this cache implementation during
- * normal operations would have a negative impact on performance.

-    // variable_set(), which updates the {variable} table and then clears the

-    // Not actually clearing the cache here therefore leads old variables to be
