Well, you both and Robert worked more on this code for PG10 than I
did, so I am fine to rely on your judgement for the final result.
Still I find this special handling quite surprising. All other AMs
just always log FPWs for the init fork pages so I'd rather not break
this treaty, but that's one against the world as things stand
currently on this thread ;)
