That looks promising.

That won't work. Consider the original sequence
        Request         Reply
        H1
        H2
                        H2
                        H1
        H1
                        H1

where H1 gets reused. I could (in fact probably would) replay this as

        H1
        H2
        H1
                        H2
                        H1
                        H1

in which case there are 2 H1s in flight, and I won't be able to match
up the replies.

I could however use (e.g.) the seek offset as the handle, and store
the original handle.
