I've been playing with some patches Christian tossed me around
JavaOne, to test out the new optimization logic that goes with the
LambdaForm implementation of invokedynamic.

So that others can play with it, I've uploaded an OS X build (Lion,
64-bit) here: 
https://s3.amazonaws.com/openjdk/openjdk8-osx-hotspot-comp-patched.tar.bz2

It ranges from about as fast as the OpenJDK 7 logic to somewhat
slower, but it's faster than non-invokedynamic logic on pretty much
all the JRuby benchmarks I've tested.

Enjoy!
