response is not coming, the socket will announce an error at poll() forcing
a close.
+Note that BSDs don't support keepalive time / probes / inteveral per-socket
+like Linux does. On those systems you can enable keepalive by a nonzero
+value in ka_time, but the systemwide kernel settings for the time / probes/
+interval are used, regardless of what nonzero value is in ka_time.
