Not so sure.
My main point is that in the realm of parallelism,
there is an increasing trend to enforce non-raciness by
construction (for a Java-based effort, see "DPJ"
http://dpj.cs.uiuc.edu/DPJ/Home.html). And again, just
because you cannot fully preclude raciness in Java does not
meant you should ignore the issue.

I don't think that we know very much about this.
There is very little experience out there with
extensive parallel usages of such constructs, and
those few parallel languages that include some form
of lambda/closure (including X10 and Fortress) do not
