About the reference count of python-side returned objects

Hi there, if I use boost_python to call a python side function and get a boost::python::object return, it seems that the reference count of wrapped obj.ptr() is at least 1 as they are set to one when created. But I don't think the reference count will be reduced automatically when boost::python::object is destructed (please correct me if I am wrong). If so, how can this memory be freed, should we manually decrease the reference count so that python GC can work? This is especially important if a large object like numpy::ndarray if returned, I am not sure whether C-side or Py-side should take charge of freeing the memory. Thanks in advance!

No repository file, test, or entry point is named. Start by reading the Boost.Python object and obj.ptr() ownership behavior, then check how returned Python objects and large numpy::ndarray values are reference-counted. Done means documenting or correcting the ownership behavior so Python garbage collection and C++ destruction are unambiguous.
