I have to correct myself a bit: the socket is in CLOSE_WAIT after receiving the clients FIN (and acknowledging it). The server hasn't yet sent its FIN, so the connection is properly "half closed", the server _could_ send some data down the line as its part of the connection is still up. Translation: the server didn't close its socket for some reason or non-reason.
For that to find out I'll have to read some code, which may or may not turn up something (interesting for me). --knitti
