You need to actually malloc the object using eg. PyFrame_New which
should be cdef declared to return object (so that pyrex handles increfs for you).

And: keep an eye on the generated c code, to make sure it's doing what you expect. (!!)

Simon.
PS. yes this is tricky, and i don't know all the details of what you will have to do.
