After 20+ years in the embedded systems arena, I'll have to disagree.
The finest real-time OSs available are proprietary, closed source
products. They weren't developed by taking a desktop or server OS and
stripping stuff out. They were not designed to maintain compatability
with old Unix apps. They were purpose-built to be small, fast, and
bulletproof. If you want to know the worst-case interrupt latency in
clock cycles, it's probably already been published. Try finding that
