Research direction

Start in the GCStats view's raw XML generation and inspect how the GenPinObj data is populated. Compare the reported fields—ObjSpaceBefore, ObjSizeAfter, PinnedSurv, In, and Out—with the available pinned-object heap data. Done means the raw XML reports the correct values for these fields.
