It is already a runnable, at least the Global shutdown ( I changed that yesterday with the "kill" button PR )

in NuBotBase there is now a callable for Startup and Shutdown. These calls are then used a futures. Futures have isDone function. This way one can either wait for completion or continue right away. Perhaps a bit cleaner is to have both procedures as runnable.

class StartupBotProcedure implements Callable<Boolean> {

class ShutdownBotProcedure implements Callable<Boolean> {

public class ShutDownProcess implements Runnable {
