Re: [RFC, 2.6] a simple FIFO implementation

[Paul Jackson]

This discussion reminds me of a fifo I did long ago, when
I had both 80386 and 68020 chips sharing the same fifo.

The key was putting both the put and get (in and out)
indices into one word, and updating them using compare
and swap (cmpxchg, I guess it's called now).

No additional locking needed.
