Yes, but I haven't had time since my cyclic_ptr work.

It seems that rather than take the route of modifying all the
standard containers one might as well just provide a special
operator new(gc) and gc_allocator that can track all the memory
blocks on the heap that might contain a shared_ptr. Then one
can either replace global operator new with the special one,
or use new(gc) or gc_allocator wherever needed.
