    Thank you for working on this @BrainLogic!
    
    First, regarding the approach proposed here:
    The approach should be able to fix the `IllegalStateException` we're encountering.
    However, I would also want to try to make `ZookeeperOffsetHandler` thread-safe and insensitive to the ordering `commitOffsets` and `close` are called from the outside. Otherwise, from the context of `Kafka08Fetcher` alone, the reason for the new synchronization isn't that obvious, and might result in harder-to-maintain code in the long run. What do you think?
