Sorry, I read the code too quickly.

So if I understand your question correctly, the chat example will
discard queued messages on a close, whereas you want the close to be
deferred until the queue is empty?

One way to achieve this is to change do_close() to check the queue. If
empty, close the socket, and if not then set a want_to_close flag. Then
change handle_write() to check the want_to_close flag if the queue is
empty, and call do_close().
