I have to understand the model. Suppose some mutable data is 
passed around between threads. I don't really know as I haven't 
read this in detail - but my question is this: is there a cost to 
accessing data across threads?

As in C or C++ I would expect the cost to be zero unless marked 
volatile.

I admit I don't understand the model of memory access in D. It 
seems that like Go, D is attempting to push a message passing 
model - that's what I meant by 'imposing a model'.
