> When ChunkUtils.writeData() finishes too fast, elapsed time for writing data
> in test case becomes zero because it's resolution is a bit rough, in
> milliseconds. That leads to the failure of test assertion that checks elapsed
> time being >0. Here, the check must be on written bytes and ops.
> I think this failure does not affect any released version, but current master
> HEAD is deterministically failing in the unit test due to this issue.
