Why isn't spinlocks turned into real mutexes such they don't prevent
preemtion in general but only other threads from entering the protected area?
That way subsystem like ReifersFS or the console driver is not blocking the
whole system but only those threads/processes calling into those things. The multimedia players will still get scheduled if it has higher priority and don't enter those areas. Just as it would in a SMP machine on another CPU.
