	global $wpdb;



	if ( null === $blog_id )

		$blog_id = $wpdb->blogid;



	$key = $blog_id . '-' . $setting . '-blog_option';

	$value = wp_cache_get( $key, 'site-options' );

	if ( $value == null ) {

		if ( $blog_id == $wpdb->blogid ) {

			$value = get_option( $setting, $default );

			$notoptions = wp_cache_get( 'notoptions', 'options' );

			if ( isset( $notoptions[$setting] ) ) {

				wp_cache_set( $key, 'noop', 'site-options' );

				$value = $default;

			} elseif ( $value == false ) {

			if ( is_object( $row ) ) { // Has to be get_row instead of get_var because of funkiness with 0, false, null values

				$value = $row->option_value;

				if ( $value == false )

					wp_cache_set( $key, 'falsevalue', 'site-options' );

				else

					wp_cache_set( $key, $value, 'site-options' );
