20447	wp_delete_user( int, $user_id ) does not flush post caches	joehoyle	ryan	"Calling `wp_delete_post( 2456, 1 )` does not flush the caches for the re-assigned posts. For example:

{{{
// assuming post 123 has an author of 2
$post = get_post( 123 );

wp_delete_user( $post->post_author, 1 );

$post = get_post( 123 );
$post->post_author; // this is ""2"", should be ""1""
}}}

This is because `clean_post_cache` is not called on the reassigned posts (see http://core.trac.wordpress.org/browser/trunk/wp-admin/includes/user.php#L259).

The best way around this I can see is get the post IDs and called wp_update_post() to let code hook in to update stuff where necessary. If performance is an issue (s wp_update_post can be slow), then I think it should at least get all the post IDs and call `clean_post_cache` on them.
