Object $conn has unnecessary data
Hi,
in method 
   public function onOpen(ConnectionInterface $conn)
   {
      die(print_r($conn));
   }

I see huuuge object of connection witch contains unnecessary objects like mail class, db connection class etc. (about 5-7 classes) which repeated in different methods.

That means my object eat a lot of memory what is unacceptable. Any ideas?
