Glad to see you've got something that works.  Don't dismiss the 
shared_ptr version automatically, though; Boost.Python can construct a 
shared_ptr for a wrapped C++ object held inside a Python object even if 
it wasn't wrapped using shared_ptr - it uses a shared_ptr deleter that 
owns a Python reference.

Of course, if there's no concern about whether the C++ object will get 
destroyed while the second Python object that refers to it is still 
alive, then your solution is just fine.
