--- Comment #38 from slw at zxy.spb.ru ---
(In reply to Michael Tuexen from comment #37)

RST+ACK, in sequence of data.
And don't do transition from FIN-WAIT-1 until got ACK to FIN.

"All segments preceding and including FIN will be retransmitted until
acknowledged." This is irrelevant to close()/shutdown().

Only after acknowledged FIN RST may generated and this RST may be w/ ACK set
(because this state is "state except SYN-SENT").
