We stumble into a case where we wanted to add timeout to Initialize() and Shutdown() because those two methods can potentially never return. In the case of Shutdow(), it seems to be happening in RequestShutdown() when the client's process has already exited. This allow for the rest of the method to be executed when the timeout is reached (important if you want to reconnect again). For the case if Initialize(), the reason is not clear, but it seems to happen in SendRequest(ClientSettings, token). It's possible that the client's process is not totally ready to accept connection. In any cases, a timeout really help in those cases.
