Eric mailed me this some time ago, so I post it here before it gets totally 
lost:

the normal way of working is:
- the client references an object in the server (thru a windows-socket, which 
is in fact a server handle)
- the server in its object references the unix-socket (fd)

however, some wait operations are done in the client by:
- retrieving from the server the unix-fd
- waiting on that unix-fd

what happens in your case is:
- server has a unix-fd opened on the socket
- client get one copy of the unix-fd (to wait on)
- client blocks on it (select)
- another thread (client) closes the windows-socket
- another thread closes the handle (from socket)
- server is called, and object is destroyed in server, hence closing the unix-
fd (from server)

at this point,
- the windows object in server for the socket is destroyed
- but the unix object (in unix kernel) is not destroyed as there's still a 
reference to it (thru a unix-fd) (the one used in the select)

Thanks
