-----------------------------------------

+1 for rebasing; I know the S3AFS class is a moving target, but regular resyncs 
will stop things divering/breaking each other

> This issue proposes S3Guard, a new feature of S3A, to provide an option for a 
> stronger consistency model than what is currently offered.  The solution 
> coordinates with a strongly consistent external store to resolve 
> inconsistencies caused by the S3 eventual consistency model.
