    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.

    Hugh
