It would also be nice to know what kinds of cycles it doesn't handle.

Sorry for the quick email... I have to go but it clears everything up the 
heap, there is no possible cyclicism.
really?

#include <boost/shifted_ptr.hpp>

#include <vector>
#include <iostream>

static int count;

struct X {
    X() {
        ++count;
    }
    ~X() {
        --count;
    }
    X(const X& other) : vec(other.vec) {
        ++count;
    }
    std::vector<boost::shifted_ptr<X> > vec;
};

int main() {
    {
        boost::shifted_ptr<X> x = boost::new_sh<X>();
        x->vec.push_back(x);
    }
    std::cout << count << std::endl;
}
