Why ? It is like sending and receiving data throught a protocol. i
will emulate AF_UNIX by tcp socket over localhost with TCP_NODELAY
No, that's exactly the _wrong_ reason for TCP_NODELAY. You simply
cannot expect message boundaries to be respected when using SOCK_STREAM.
So, either sendfd/recvfd must be documented to work only on SOCK_DGRAM
sockets, or they have to be rethought (if possible at all).
