> In {{ErasureCodingWorker}}, for the same block group, one task doesn't know
> which internal blocks is in recovering by other tasks. We could end up with
> recovering 2 identical block with same index. So, {{ReplicationMonitor}}
> should wait previous work to finish before schedule another one.
> This is related to the occasional failure of {{TestRecoverStripedFile}}.
