   @soarez The `Log.loadSegments()` call happens in `Log` [constructor](https://github.com/apache/kafka/blob/2.6/core/src/main/scala/kafka/log/Log.scala#L287). I'm curious how would the `segments.clear()` call from there race with the `kafka-log-start-offset-checkpoint` periodic work, because the periodic work can't see the `Log` instance until it is [instantiated](https://github.com/apache/kafka/blob/2.6/core/src/main/scala/kafka/log/LogManager.scala#L769-L784) and made discoverable by adding to `LogManager.currentLogs` and `LogManager.futureLogs`.
