The problem comes up if the reason for the interrupt is gone away before 
the VIC could ack it. This happens mainly because the interrupt was 
disabled in the peripheral.

Changing CPSR could not provocate such.

But having a default interrupt handler installed is good practice (or 
defensive programming) anyway.

(Same as initializing _all_ peripherals, not only those used.)
