   Thanks for taking this on, Tom!
   
   This seems fairly involved and I'm wondering if there's a simpler solution. The changes here cause `DistributedHerder::start` to block on the completion of `DistributedHerder::startServices`, which is invoked on a separate thread. If we want to retain this blocking behavior, could we move the invocation of `DistributedHerder::startServices` into the `DistributedHerder::start` method? I'm thinking something like this:
   
   ```java
   public class DistributedHerder extends AbstractHerder {
     @Override
     public void start() {
       log.info("Herder starting");
       startServices();
       log.info("Herder started");
   
       this.herderExecutor.submit(this);
     }
   }
   ```
