 ------------------------------------------------  
   
 With the revamp of the kernel concurrency model, much of the kernel is fully  
 multi-threaded and can therefore be preempted at any time. In support of  
 lower context switch and dispatch times for real-time threads, full kernel  
 preemption is being implemented.
