QNX is a real time, Posix compatable operating system based on the a micro-kernel architecture. This posix operating system has a very small memory footprint, and crops up in no end of embedded products.

Unfortunately, while being dependent of gnu tools for it's development, it is released under a proprietary license. This OS has progressed to the point where it is stable, mature and self-hosting for development work.
