When a player is destructed don't to any telnet, input_to or command handling for it, because it may result in calling a function into a destructed object (and thus yield a fatal error). Usually destructed players are removed before the call of get_message(), but newly created connections or handling telnert negotations may result in freshly destructed objects in the list of open connections.
