Claude:
The spec
http://www.w3.org/TR/sparql11-federated-query/#serviceFailure
says
"""
The failed SERVICE clause is treated as if it had a result of a single solution
with no bindings.
"""
I think this is because it allows the query to continue whereas SILENT
returning no rows, would cause patterns to stop executing when joined together.

> in nextStage() when a RuntimeException is caught and the 'silent' parameter
> has been set, a QueryIterSingleton is created. This results in an empty
> solution being returned. I think the proper action would be to return a
> QueryIterNullIterator so that the empty result is not returned.
