When you're trying to eke out every last bit of performance, that's fine. However, I tend to shy away from using VM-based solutions (Java, Python, even .NET/C#) when they are tied to a platform. If I *must* do so, I farm out the platform-specific pieces to a library, and my main app gets some code added that knows how to load libraries on the fly. 

When feasible, mind you.
