In those cases, create a copy of the request so that someone who is inspecting the delayed snoop can also inspect the request still. All of this is rather hacky, but the allocation / linking and general life-time management of Packet and Request is rather tricky. Deleting the copy is another tricky area, testing so far has shown that the right copy is deleted at the right time. |
