+* Version 1.7 can't create wp-config.php when installing with WordPress 4.0
+
+ When install process notices that there's no wp-config.php, it tries to
+ create one from wp-config-sample.php. During that time, WordPress unsets
+ global $wpdb and calls require_wp_db() function.
+ That function newly instantiates wpdb class. SQLite Integration has no
+ way of intercepting that process.
