no - the interrupt interception does not prioritize interrupts - I played
with it as it is fairly simple to implement but it really has close to 0
advantage as the you simply can run the hig priority ISR with disabled 
interrupts, as it will preempt any other running ISR this de-facto has the
same effect as if you would prioritize interrupts. The overhead of 
introducing interrupt priorities does not pay off if you keep your ISRs
short and shedule a "bottom-half" as a regular RT-thread.

In what situation would you need it ?
