91 // * The PacketImpl destructor will *explicitly* clean-up the interpreters_ list by removing
92 // each element from the list and deleting it if it's (intrusive) refcount is 0
93 // * The PacketInterpreters use safe hooks -> they know whether they are part of a list or not
94 // * PacketHandle has an intrusive_ptr to PacketInterpreterBase. The intrusive_ptr_add_ref
95 // will refcount both the PacketImpl as well as the PacketInterpreterBase
96 // * intrusive_ptr_remove will only delete the object if it's not in a container
