+ * Saves the session, in case it is still open, before sending the response/headers.
+ *
+ * This ensures several things in case the developer did not save the session explicitly:
+ *
+ *  * If a session save handler without locking is used, it ensures the data is available
+ *    on the next request, e.g. after a redirect. PHPs auto-save at script end via
+ *    session_register_shutdown is executed after fastcgi_finish_request. So in this case
+ *    the data could be missing the next request because it might not be saved the moment
+ *    the new request is processed.
+ *  * A locking save handler (e.g. the native 'files') circumvents concurrency problems like
+ *    the one above. But by saving the session before long-running things in the terminate event,
+ *    we ensure the session is not blocked longer than needed.
+ *  * When regenerating the session ID no locking is involved in PHPs session design. See
+ *    https://bugs.php.net/bug.php?id=61470 for a discussion. So in this case, the session must
+ *    be saved anyway before sending the headers with the new session ID. Otherwise session
+ *    data could get lost again for concurrent requests with the new ID. One result could be
+ *    that you get logged out after just logging in.
+ *
+ * This listener should be executed as one of the last listeners, so that previous listeners
+ * can still operate on the open session. This prevents the overhead of restarting it.
+ * Listeners after closing the session can still work with the session as usual because
+ * Symfonys session implementation starts the session on demand. So writing to it after
+ * it is saved will just restart it.
