is it a faq error ?
Andrei is a proponent of having shared to memory barriers, I disagree
with him. We haven't convinced each other yet, so this is a bit up in
the air.
Wait, then what would shared do? This is new to me as I've always
assumed you and I have the same view on this.

I'm speaking out of turn, but...
I'll flip that around: what would shared do if there were memory barriers?
Walter has said previously in this thread that shared is to be used to
mark shared data, and disallow any potentially non-thread-safe
operations. To use shared data, you need to manually lock it and then
cast away the shared temporarily. This can be made more pleasant with
library utilities.
It cannot unless some ownership is introduced in D.
