Re: [rtl] share memory again

[Norm Dresner]

There's no real processing overhead on shared memory, the data is just
there and any process can access it.  OTOH, using FIFO's makes the
data less corruptible by random pointer errors in your code.

If speed is your main concern, I'd go with shared memory.
