Also (from an early attempt at a cookbook):
  http://hg.openjdk.java.net/mlvm/mlvm/file/tip/netbeans/indy-demo/src/recipes/FastAndSlow.java

This uses the same logic as Remi's safeAdd.

What's needed here is a way to get 33 bits out of a 32-bit add intrinsic.  There's no fully natural way to do this, and about 4 kludgey ways.  Because there are so many poor ways to shape the API, it's hard to pick the best one to invest in.
