> writable sockets
The goal of NGINX here is not to measure whether a socket can consume any data whatsoever. A connection that consumes 1 byte every 15 seconds is still considered stalled, and should be killed. Using the time between sendfile invocations is not the goal, it's a means toward implementing a minimum rate, and they implemented a minimum rate the wrong way. It's an X Y problem and that's not the kernel's fault.
