    Whirlwind (now) does very little. It's more of a framework which is pretty much
    ready now for optimizations to be added to it.

    But this system looks pretty decent. They pretty much do things the way I would
    have built them. They have an ahead-of-time static compiler/whole-program
    optimizer + a run-time compiler + a persistent cache of dynamically generated
    code for reuse on future invocations of that Java program. They even mix
    whole-program static analysis with support for dynamic class loading &
    reflection. Not many details on how, though...
