Looks like the introduction of CCS records in the client second flight gave time to s_server to send NewSessionTicket messages in between the client application data and close_notify. There seems to be no way of turning NewSessionTicket messages off, neither by not sending a psk_key_exchange_modes extension, nor by command line flag. Interleaving the client write like that tickled an issue akin to #18701: on Windows, the client reaches Close() before the last record is drained from the send buffer, the kernel notices and resets the connection, cutting short the last flow. There is no good way of synchronizing this, so we sleep for a RTT before calling close, like in CL 75210. Sigh.
