Fwiw posix specifies readv and writev already; you may want to take a look at those.

It's not really the same, though; readv and writev are still synchronous APIs, they just do more at once.

I'm aware of readv/writev. This was supposed to cover much more, because it is with arbitrary syscalls. Open a file and if successful read from it - all with a single syscall. Another example: socket, setsockopt, bind, listen, accept in a single syscall.
