Parallel-safe lambdas

I think an important driver for this whole exercise is that without
some way to make the parallel array API more manageable, it will be
left out of JDK 7--which means it may not show up for another 2 or
probably 3 years, till JDK 8. That's a lifetime in technology
innovation, these days. Personally, I'm all in favor of having a
highly targeted usage scenario driving this project.
