Dmitry,

If the jump to zero will be detected, it is preferable during
development, so the spurious interrupt can be cured. (I tend to light an
LED, and loop endlessly.)

In production, your proposal is what I do, to maximise robustness of the
delivered product.

Mind you, I've always written my ISRs in assembler so far, so what is
done won't impact me much. ;-)

Erik
