You seem to be using "Real-Time" in some special technical way, as
opposed to the general definition "meeting the application timing
deadlines".

Using the general definition, if your application has deadlines with
tolerances on the order of 0.1 seconds, then the answer is clearly
"yes".

For tighter tolerances, you'd have to measure the actual performance,
and possibly use an enhanced kernel as you discussed.
