Thanks for the nice explanation. It's nearly what I've thought (though I
didn't read it anywhere so was not sure). Only with my client/server
application (winsock2...) TIME_WAIT state is not used at all if the
client closes first.

What I don't know for geckook's example is which side closes first, but
that would be interesting to see...
