Bringing back the old functionality that was mistakenly removed when the connection cache was remade. When creating a new connection, all the existing ones are checked and those that are known to be dead get disconnected for real and removed from the connection cache. It helps the cache from holding on to very many stale connections and aids in keeping down the number of system sockets in wait states.
