I've looked at v5, and the retry/recheck logic seems OK to me - I'd
still vote to keep it consistent with what pg_basebackup does (i.e.
doing the LSN check first, before looking at the checksum), but I don't
think it's a bug.

I'm not sure about the other issues brought up (ENOENT, short reads). I
haven't given it much thought.
