How would SO_KEEPALIVE help?  The other end is deliberately closing
the connection and we need to know that.

Would a non-blocking read() followed by a poll()/select() be useful?
We'd still get a 0 back from read() - but if it was the EOF, would the
state of the socket change to be in the 'exceptional' state then if we
repoll?  -- justin
