So what were you saying about processor interrupts? That it is not a problem that they can prevent useful progress. Actually, this is a recognized problem, you just had to search harder for the standard literature that names it. It is called “interrupt storm.” Although, one may be led to believe that the negative consequences of interrupt storms are entirely operating system problems, given practical rate limits in devices sending interrupts. Or is this not true? Is it really true that the hardware can generate interrupts in a way that is totally impossible for software to properly handle? Well, I don’t know, but the general problem associated with this is well-recognized.
