If you close a unix domain socket from the client, is there a reason the "IO::Socket::UNIX::connected()" method never detects the close? See the comment over the while loop below. 
use IO::Socket::UNIX;

my $sockfile = "/tmp/testsocket";
if (fork) {
    my $server_sock = IO::Socket::UNIX->new( Type => SOCK_STREAM,
                                             Local => $sockfile,
                                             Listen => SOMAXCONN );
    my $req = $server_sock->accept;

    # This loop never exits.
    # The close done from the client is never detected.
    while ($req->connected) {
        print STDERR "connected\n";
    }
    print STDERR "disconnected\n";
}
else {
    sleep 1;
    my $client = IO::Socket::UNIX->new( Type => SOCK_STREAM,
                                        Peer => $sockfile );
    close $client;
    exit;
}
