>
> There are two potential issues with current approach:
>  # A next locker wait future is completed in the same thread. This means the 
> whole lock queue will be processed by a single thread and can introduce 
> starvation.
>  # This method can be called from a sensitive thread (like jraft STM updating 
> thread), worsening first case.
> This can cause latency issues in contented scenarios. It looks more safe is 
> to invoke the next locker asynchronously. Needs performance testing to figure 
> out best behavior.
