No, we only get the single RST after the FIN from the Mac side which
is dropped. I would have expected the RST from the Mac after the
retransmits, but we don't see any further transmits from the Mac.
And the linux socket stays in CLOSE-WAIT (i mistakingly said
TIME_WAIT above).

For reference, I put the packet exchange in my initial mail.
