Writing a driver for perl6 I found that when I want to use runCommand to shutdown a server, the server will not respond to it when it is really going down. In that case I must check if there are any bytes send back to know that it did shutdown. It is much cleaner and consequent to sent a last {ok: true}. I presume that when the server could not shutdown it would send a message {ok:0} with whatever reason. This case exists otherwise it was not necessary to have a {force:1} option.
