Do you want something like an actual chat server where connection close 
can occur at any arbitrary time unrelated to data transmission, or 
something more like HTTP/FTP where you know in advance that you want to 
close the connection immediately following a particular transmit?

Because these two patterns have different solutions, and the ones being 
discussed in this thread so far are mostly the former while the one you 
mentioned in the last quoted paragraph above is for the latter (and is 
much simpler).
