    Then the bug is still not fixed by setting it, since your total
    send size might be less than `sysctl net.inet.tcp.sendspace`.

    You guys should really just have a buffer finalize function
    that gets called on block/return cases, and impute the flags
    you need on the socket while it's being used for sendfile.
