I'd looked at one of the Stevens books, specifically the implementation of soclose(), but it seems I misread it. Re-reading the documentation posted here, I agree, the socket must continue to shutdown gracefully. (An application might then reset the linger option so that the socket is reset... it might be nice to have a simple API by which to request "linger upto N seconds, then give up and reset the connection".)
