It's this guy's hobby kernel project. Everyone's gotta have one. He's been working on it for 5 years or so. You're surely not asking for apples-to-apples comparison with production quality operating systems?

But compared to other hobby/DIY operating systems, this seems to be a fairly complete system with a real userspace and ports of real applications. Which makes it much more finished than 99% of similar projects.
