Threaded IRQs are no magic bullet. They can only help to push a problem
down the priority ladder, curing a problem symptom where possible.

Nevertheless, threaded IRQs for RTDM are planned. The yet open design
challenge is how to support driver writers best when they have to switch
between both models, e.g. during compile-time (keep in mind, you also
have to switch the locking: spinlock<->mutex).
