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. -- Terry
