Faced with porting a message-based system of 4 processes from UN*X 4.x+
on a 11/70 to Unix 3.0 on an 11/34, which couldn't fit messages into the
kernal because of the address space limitations, I was able to emulate the
message facility in a compatible fashion using NAMED PIPES.  The only feature
I didn't emulate was the limitation on message queue length, but that was
not really a problem since UN*X buffers up to 10 blocks onto disk if necessary.
