the need to ensure each task completes in less than one tick time
What a nightmare maintenancewise. Just visulaize: some task "cross the edge" when 5 random facts concur (i.e. once a month or once a year) and the poor sod that is tasked with fixing it has the chance of a tailor in hades of reproducing it. A time triggered sheduler only runs one task per tick so this situation never occurs unlike interupt driven systems where you have no control over when things happen. I thought the proponents of RTOS said it eased maintenance.
