This is O(n) over the number of buffers. It's common that only a limited number of buffers is written at a time (e.g. 1024 for `writev(2)`). `write_vectored_all` will then call `write_vectored` repeatedly, leading to a runtime of O(n²) over the number of buffers. The fix is to only calculate as much as needed if it's needed.
