One of my sideprojects is intended to address this: https://lwn.net/Articles/976836/

The idea is a syscall for getting a ringbuffer for any supported file descriptor, including pipes - and for pipes, if both ends support using the ringbuffer they'll map the same ringbuffer: zero copy IO, potentially without calling into the kernel at all.

Would love to find collaborators for this one :)
