2 - remote host TCP connection close
due to RST, all other cases in which
the socket is aborted without
indication from peer (for instance
because peer doesn't send ack after
maximum number of retransmissions/
peer is no more alive). All these cases
include all the "FATAL" errors after
recv or send on the TCP socket (named
as different from EWOULDBLOCK)
3 - socket inactivity timeout

Not yet acknowledged data are available only for TCP connections.
The value <ack_waiting> is always 0 for UDP connections.
