Garbage Collection and Skipped Turns

I've actually been debating writing a Robocode simulator to make robot profiling much easier. What it would do is to pretend to run a robot battle with your robot against either another opponent, or perhaps some imaginary robot, using a combination of mock objects and simulation. It would run without any security at all, no sandbox, nor would their be skipped turns, so you would only want to run it with trusted robots. But it would be much easier to run a profiler against. The simulated battle may not be a perfect simulation, but as long as it's close, it should work and be useful.
