https://github.com/apache/incubator-rocketmq/pull/31
When I use ASYNC_MASTER,there was the same problem,Because HAService also
has `this.waitForRunning(0)`,whether SYNC_MASTER or not.
When you said that the `GroupCommitService` may miss some notify signals,I
think it's right.So I think wait time to be 10ms is acceptable.
