> Starting up an RPC server is done in two steps.  In the constructor, we instantiate the RPC server.  Then in startServiceThreads() we start() it.
> If someone RPCs in between the instantiation and the start(), it seems that bad things can happen.  We need to make sure this can't happen and there aren't any races here.
