There exist natural real time tasks like serial receive buffers in Linux. Then I started to work a few years ago programming an 8-bit micro controller they did not have nested interrupts with priority while some of the new ARM cortex-* CPUs used in many micro controllers have today. To put it another way: With priorities handled correct for interrupts all work appropiate for this priority level could be done within interrupt handler. Old style without priority is to exit interrupt handler as soon as possible which still may hold off higher priority tasks and shuffle away work until later but then should it be done?
