Nice writeup, but I don't understand how `curl` didn't trigger bug for them (or any other hyper HTTP server out there), given the explanation in the article.

`curl --http1.1` sends `Connection: Close` so sender (hyper) must attempt to shutdown connection after sending whole body. Surely any network is slower than memory copy into socket kernel buffers, so it must reliably trigger condition "buffer flush can't be done in one go" and thus trigger early TCP shutdown.
