This is not completely true, also Py++ always provides an explanation
why it does this.

Py++ has transfer_ownership_tester.py. You welcome to play with it.
I don't completely understand the issues related to
boost::python::wrapper class and auto_ptr as held_type. I found that
the whole mechanism doesn't work as expected.

For me std::auto_ptr<MyTestClass_Wrapper> worked fine.
