    Description

      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.
