[C++-sig] boost python and shared_ptr

[Denis]

Hi, sorry for my English,
but I hope you will understand and help me find solution.
Thanks!
there are C++ (pseudo) code:

class A
{
public:
     void test()
   {
       printf(__FUNCTION__);
   }
}

shared_ptr<A> gA;
shared_ptr<A>  GetA()
{
             return gA;
}

//wrapping code:
class_<A, shared_ptr<A> , boost::noncopyable> ("A")
       .def("test", &A::test) ;
def("getA", GetA);


and Python code:

a = GetA()
a.test()  #works

proxy = weakref.proxy(a)
proxy.test()  #works

del a 
proxy.test() # failed!!!
#but object is still live in C++

please help me fix it.
I know it is not Python/Boost  bug, it is correct behaviour.

What I want?

I want to create PyObject for every object from C++  and save it inside 
of my C++ class.
something like this(pseudocode):
class A  {   object _self;     };

if (a->_self == 0)
  a->_self = makePyObjectForExistingClass(this)
return _self


and this PyObject should be deleted automatically when object will die 
in C++



Thanks!
