But if compiler memory actions from before the call to start() to
after the call to start(), you are still screwed.

This point is important to mention because all of these memory model
issues involve the interaction of the compiler, native libraries and
processor architecture.

I'm hoping we are safe on this one. But we need to be careful about
what gets done in the compiler.
