ouch! that comment about hard realtime is plain wrong.
hard realtime is used in systems where you need minimal delay, like engine
controls, medical systems, etc.
imagine your life support systems would use hard realtime that can delay up to
a week .....
the most important aspect of hard realtime systems (like rtlinux) is that they
have the lowest latency possible!
