I guess you would need something to recv() into a pre-allocated
buffer. That would need some patches.

Would be nice to have though. E.g. a server that saves data to a file
using Linux aio needs data to be page aligned. Providing an
alloc_buffer_hook that uses posix_memalign with the right flags would
allo data to be received, passed through all the pipes and then
written to disk without the need to copy it.
