(*os.File).Fd() implicitly sets file descriptor into blocking mode [1], [2] We avoid that by calling (*os.File).SyscallConn instead. This method was added in go1.12 (released on 2019-02-25) [1]: https://pkg.go.dev/os#File.Fd [2]: https://cs.opensource.google/go/go/+/refs/tags/go1.20.3:src/os/file_unix.go;l=80-87
