Backport #29532 by wxiaoguang

Without case <-t.C, the workers would stop incorrectly, the test won't pass. For the worst case, there might be only one running worker processing the queue items for long time because other workers are stopped. Thanks to oliverpool for looking into the problem and proposing a fix.

Actually, the real problem is not completely fixed, the root cause is not directly related to the ticker, but is related to the logic of doDispatchBatchToWorker. It isn't a serious problem at the moment, so keep it as-is. More comments are added.
