When I use code which parallels this structure, I see the Model

That is because by default arguments are passed by-value. If you want
something else, you need to specify a return-value policy, such as
manage_new_object.
Is there a return policy I need to provide? I am confused by the way
the destructing class is new'ed in c++ code, not in python by using
exposed c++.
boost.python wants to pass a Model, and thus makes a copy. from the
object you pass back, then destructs it.
