> This class has a grpc observer that queues recieved messages on a LinkedBlockingQueue and then has a separate thread pulling from the the queue to add to an executor.
> Instead we could just add directly to the executor from the grpc stream, as the executor by default has an unbounded queue size (and there are comments indicating that a limited size executor can cause deadlocks otherwise)
