wp_cache_delete not work with options autoloaded

Sorry for my bad english but I’m french..

when I want to delete an autoload option (with the autoload column is set to ‘yes’) from the cache, this not work.

why? because the wp_cache_delete function not delete the cache of the $alloption array. But get_option try to get option in this array.

function get_option($setting) {
	...
	$alloptions = wp_load_alloptions();

	if ( isset($alloptions[$setting]) ) {
		$value = $alloptions[$setting];
	} else {
	...
	return apply_filters( 'option_' . $setting, maybe_unserialize($value) );
}

function wp_cache_delete($id, $flag = '') {
	global $wp_object_cache;

	return $wp_object_cache->delete($id, $flag);
}

class WP_Object_Cache {
	...
	function delete($id, $group = 'default', $force = false) {
		if (empty ($group))
			$group = 'default';

		if (!$force && false === $this->get($id, $group, false))
			return false;
	...
	}
}

And the WP_Object_Cache::get() don’t get the option in $alloption array.

right ?
