[vtkusers] Best strategy for appending poly data

[Petru Pau]

I have a question for people who have knowledge about vtkAppendPolyData.

I am using this class to append lots of vtkPolyData generated by
some algorithms. And I mean lots: thousands.

Currently I append as soon as the new poly data is computed.

Is this the best strategy? Would it be better to use, say, 10 appenders,
and at the end append their outputs?
