Our application is a raytracing renderer. Storing data for each object
encountered in a scene that contains ~100,000 objects is a problem.
 Some of the data are in scoped_arrays of scoped_ptrs. If we had to
double the size of those arrays just to get a feature that we don't
need, I would copy the current scoped_ptr code and make it my own.

I couldn't take the memory waste, even if it were only another 50 MB.
 We work very hard in every other way to use memory frugally, so that we
can support larger scenes, which our users continually demand.
