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. paul
