If you're coding pointers into request IDs you better make that
explicit and add lots of comments explaining why that's OK and
why it's going to work fine in these circumstances.

I'm not applying this patch, it just makes a bad situation even
worse.  Either your request IDs are 64-bit or they are not, it
can't be both.
