Review comment:
The `Status error` parameter itself, isn't very useful, since all S3
errors seem to result in the same IOError code. Having access to the AWS/S3
error code here would be really useful.
Any objections to adding that as a third argument to these methods? It could
be casted as an int to avoid having to include any aws headers here.
