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".)
