Ostensibly, using a shutdown(SHUT_WR) and then a wait for a recv return
of zero would take about the same length of time as polling local
connection stats to see that there were no ostensibly unacked data -
both will take one RTT right? and shutdown/read has the added property
that it will deal with zero windows automagically.
