I think that we are "on the same page". If the interrupt is already masked out, then Safe doesn't have to do anything, but it is likely that this critter does things that it doesn't need to do. "polite" would mean not doing anything with something that was already meant to have nothing happen.

It could very well be that there is no "safe" way to call Safe if the user programs wants to handle a signal.
