I shall ignore this v3 completely: "git send-email" is a wonderful
tool for mailing out patchsets in quick succession, but I have not
yet mastered "git send-review" to do the thinking for me as quickly.

Still deliberating on 4/9 and 9/9 of v2: they're very close,
but raise userfaultfd questions I still have to answer myself.
