Could you elaborate a bit on what you mean? What state would you give to
clone_allocator? Keep in mind that clone_allocator needs to, at some point,
be implemented IN the DLL itself, otherwise the correct 'delete' will not be
called. Some sort of polymorphism would solve this, that's the most obvious
solution I can think of. Either that, or instead of a functor, take a
boost::function, and that way I can pass you a function pointer to call for
clone allocation/deallocation. There's several easy ways of solving this
particular issue that I can see.

But I would be interested in hearing more about the idea you have. I'm not
sure I fully understand just yet.
