> We can make the fact that some {{FileSystem}} implementations are really 
> blobstores, with different atomicity and consistency guarantees, by adding a 
> {{Blobstore}} interface to add to them. 
> This could also be a place to add a {{Copy(Path,Path)}} method, assuming that 
> all blobstores implement at server-side copy operation as a substitute for 
> rename.
