Is there any way that I can create a shared_ptr that will call this special library free function when the last copy is destroyed?
Yes, there is:
shared_ptr< blob > pb( create_blob(), free_blob );
[Nat] It might be worth binding that knowledge into a specific shared-pointer-to-blob type so that the required deleter function is implicitly captured EVERY time you construct such a pointer.
