Interesting.
The "Software engineering postscript" contains a justification for
priority based RTOS design that's filled with misstatements.
Competently implemented round robin schedulers do not (cannot) fail in
the bizarre ways claimed; in fact failure modes like that are common
to interrupt driven (priority) designs. It's disconcerting to read
misinformation of that magnitude.
