When importing modules like "Foundation" or "Appkit" in Python, big files with metadata are loaded up. As long as you import those modules, you'll get this high memory usage. Addressing this problem is on PyObjC's roadmap, but its maintainer, Ronald, is pretty much the only one working on it, so development is slow.

If you want to reduce memory usage, you might have to convert a part of your code to Objective-C, yes. I wrote an article about that a while ago: http://www.hardcoded.net/articles/embedded-pyobjc.htm

No, it's licensed under MIT.
