JE: are you sure about that? AFAIK the only way to get recursive
interrupts (interrupt while still in the interrupt) is explicitly
re-enabling interrupts within the interrupt code.

Returning from the interrupt whithout clearing the interrupt source
would cause a perpetual interrupt: immediately after an interrupt the
main code would be interrupted again. Not nice, but definitely not the
same as recursive interrupts. For the guru's: would the main code
execute 0 instructions, or 1, or maybe even more?
