 From what I know, priority ceiling multithreading adresses problems
like this exactly. With a high priority disk access and decoding, it
wouldn't be possible to interrupt the playback. Since the implementation
of real OSEK multithreading is very challenging, it is possible to use
ready made (and certified) solutions for microcontrollers. Correct me if
I'm wrong, please.
