The asynchronous IO programming paradigm is more intuitive. No select loop needed. You just launch a number of AIO requests, do whatever else you want, and if you need the data you wait for the AIO completion.

Moreover, between the aio submission and its completion the associated buffers belong to the kernel. That is why 0-copy basically only works this way.
