> BMI pass a iter of inner buffer to AccessProcess to take the undealt
> mutations, AsyncProcess call iter#next to get the mutation and then call
> iter#remove to delete the mutation from inner buffer. Hence, There's a good
> chance that the mutation is processed repeatedly in case there are a bunch
> of threads which are running the flush.
