Still crashity crashing

[Attila Szegedi]

Okay, uploading a new build. URL is <http://files.getdropbox.com/u/362958/mlvm/mlvm-macosx-i586-20090804.tgz

I can now confirm that it indeed does work with jruby-1.4.0dev that  
indeed emits invokedynamic.

The only catch is, it's very slow with invokedynamic, something that  
Christian also mentioned.
