Ah, I see. I tried to do this by copying what gstbuffer does, which is
to use the private interface to gstdata. Because you have to chain up to
gstdata, perhaps we need to implement our own minimal object model on
top of GTypeClass (no signals, no properties, perhaps only shallow
inheritance). It would take some tests to see how efficient this would
be.

This is 0.9 material, of course.
