Well, I personally would rather see that nobody ever needed RTlinux at
all. I think hard realtime is a waste of time, myself, and only to be used
for the case where the CPU speed is not overwhelmingly fast enough (and
these days, for most problems the CPU _is_ so overwhelmingly "fast enough"
that hard realtime should be a non-issue).

I definitely agree with low-latency requirements even in a standard Linux.
I just disagree violently with doing them with horrible cludges instead of
working on doing it right.
