So many people get this wrong, they want to make "real time" in Unix "good

And you know what sucks? I was on the Usenix review committee and I gave
it 2 thumbs up but someone else, looking at you, Rob, said it was not
interesting because the real time kernel wasn't POSIX. Even though the
real time kernel had pipes, signals, and shared memory with Linux.
He was a bigger deal than me so it didn't get published.
I love the Rob in question, not Pike, but this was one of the most bone
headed calls I've ever seen him make. The world needed to see this.
Wind River bought it and buried it because it competed with their stuff
that was nowhere near as good.
Clem should pay attention, in my opinion, this is
how you do Unix and
real time. Because Unix is time sharing and throughput, that is the
opposite of what real time is. Wedging real time into Unix is a mistake.
Agreed.
