In this case I disagree. Given shared global memory and peripherals in
the SoC case, any IPC or shared-memory setup is destined to create
performance or management overhead.

When there's independent nodes connected via CAN/LIN/FlexRay, then I
agree that multiple processes communicating via UNIX sockets make a lot
of sense.

My use case here is testing and debugging, so I think we could live with
the blocks being executed in an interleaved fashion until someone has
the ultimate parallelization solution for upstream.
