since https://github.com/symfony/SwiftmailerBundle/pull/64 flushing the memory spool manually is not necessary anymore when using Symfony 2.3+. I added a versionadded note here, but we might decide to remove the obsolete paragraph instead, making the cookbook only about generating urls (which would require renaming the page then)
