I am not an expert in the proxy magic of Gelly, but it looks fine to me.
From my side, feel free to merge at your discretion...
> Don't proxy a ProxiedObject

> Issue Type: Bug
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan

> Fix For: 1.1.0

>
> Some graph algorithms pass through a DataSet unmodified (at least, until we
> have VertexSet and EdgeSet). We need to prevent a DataSet from being proxied
> twice. Allowing two methods to own a single object sounds brittle, so we can
> instead provide access to the original DataSet which can be wrapped in a new
> proxy.
