You may see some errors from the Go RPC package that look like rpc.Register: method "Done" has 1 input parameters; needs exactly three. Ignore these messages; registering the coordinator as an RPC server checks if all its methods are suitable for RPCs (have 3 inputs); we know that Done is not called via RPC.
