Ingo, how relevant is that "350 nsecs on current hardware" claim?
I don't mean that in a bad way, but my own experience suggests that most people doing real hard RT (or tight soft RT) are not doing it on x86 architectures. But rather on lowly 1GHz (or less) ARM based processors and the like.
For RT issues, those are the platforms I care more about, as those are the ones that get embedded into real-time devices.
