> This is a follow-up from KAFKA-3092. The shortcut exit from awaitShutdown() 
> in WorkerTask can lead to an inconsistent state if the task has not actually 
> begun execution yet. Although the caller will believe the task has completed 
> shutdown, nothing stops it from starting afterwards. This could happen if 
> there is a long delay between the time a task is submitted to an Executor and 
> the time it begins execution.
