    He wants the connection to be closed after a certain number of seconds if it is
    idle.

    Lefterius, when you read() from the socket, call time(). If you read more than
    zero bytes, save that time in a variable. If you read zero bytes, compare what
    time it is now to the saved value, and if the delta is greater than when you
    want an idle connection to close, well, call close() and exit or whatever.

    Details like initializing the variable to now beforehand are probably needed.
