If a client connects and doesn't issue a request, then 408 is indeed the
better choice here.

If the client did send a request and the server takes too long to
respond (for example a CGI does not complete), then returning a 522
might be appropriate.

I've updated the homework assignment on the website to indicate that
either code may be suitable.
