Closing Copies of Result Sets

[graham]

Hi

I have a copy of a result set, made by doing
    try (QueryExecution qexec = QueryExecutionFactory.create(query, model))
    {
                ResultSet results = qexec.execSelect();

                return ResultSetFactory.copyResults(results);

    }

I presume I don't have to close the copy of the result set since it's in 
memory?

Likewise if I have an in memory Model which I query by exec-ing a SPARQL 
query as per the above (without the copy), I presume I don't have to 
close that either?

thanks

graham
