What is it supposed to do?

From what I saw, works fine for me (without anything running on localhost:80, it dies with IO::Socket::INET: Timeout)

I don't own lincoln's book.

update: Anyway, check this out

# from perldoc IO::Select, w/sprinkles by me
    use strict;
    use warnings;
    use IO::Select;
    use IO::Socket;
    my $lsn = new IO::Socket::INET(Listen => 1, LocalPort => 8080);
    my $sel = new IO::Select( $lsn );
    my $new;
    warn "about to enter while";
    while(my @ready = $sel->can_read) {
    warn "in while";
        foreach my $fh (@ready) {
        warn "in foreach";
            if($fh == $lsn) {
            warn "creating a new socket";
                # Create a new socket
                $new = $lsn->accept;
                $sel->add($new);
            warn "added new";
            }
            else {
            warn "processing socket";
            warn "read 10 characters and echo them";
            read($fh,$_,10);
            warn "here they are '$_'";
                # Process socket
                # Maybe we have finished with the socket
                $sel->remove($fh);
                $fh->close;
            warn "done with it, neext";
            }
        }
    }
