> When I am debugging Jena-based code and mouse-over a dataset variable, the system basically hangs. It seems that the toString() method of DatasetGraphBase is producing a complete rendering of the whole dataset using WriterGraph.output(out, this, null). And our datasets typically contain thousands of named graphs, some of which are quite large. 
> This is handled much better in places such as GraphBase.toString, which terminates after a certain number of triples.
