> I haven't seen this bug in practice, but I was thinking about this a bit and 
> think there may be a correctness issue with the way that we handle client 
> batches which contain multiple operations which touch the same row. The 
> client expects that these operations will be performed in the same order they 
> were submitted, but under contention I believe they can get arbitrarily 
> reordered, leading to incorrect results.
