Sounds a bit like QNX actually

Is QNX used anywhere? Sounds interesting.

It's in millions of devices. Blackberry acquired them IIRC. You don't run across it much on HN because it's a standard commercial license.

Lots of infotainment in cars use QNX, along with aviation.

Also medical devices

I’ve seen other comments describe QNX being used in embedded systems needing rock solid performance.
