FakeClock keeps an internal list of messages to be executed to ensure deterministic serialization. The next message from the list is triggered by a separate helper message sent to the real Handler. However, if the target HandlerThread is no longer alive (e.g. when it quit itself during the message execution), this helper message is never executed and the entire message execution chain is stuck forever. This can be solved by checking the return values of Hander.post or Handler.sendMessage, which are false if the message won't be delivered. If the messages are not delivered, we can unblock the chain by marking the message as complete and triggering the next one. PiperOrigin-RevId: 491275031
