What's the saved state used for? I'm guessing that maybe it's used to resume execution of the original context after the other context finishes executing. Is that right?
Right! It saves the register of the cpu (like stack pointer instruction pointer etc.). The context must not necessarily finish its execution it can decide to suspend itself - its state is saved and may be resumed later (e.g. it continues its work if resumed). Oliver
