TaskConnectionHandler.unregisterSocket

Called by finalize to unregister the connection socket from epoll before closing it. This is done because closing a socket does not always mean that it is unregistered from epoll -- in situations where the process has forked, the fork's reference to the underlying kernel file description will prevent it from being unregistered until the fork exits. Therefore, to be certain that the socket will not fire again in epoll, we need to explicitly unregister it.
