I don't know for sure, but could it be that there is no assurance that it's key was key 8? There are indicators in the books that programs can run in keys 9 through 15.

I appear to have guessed wrong. I just wanted to do a reality check to make sure I had not fat-fingered something: typically a program in Key 8 does *not* have a PSW-key-mask bit of one for SPK 8 in Control Register 3? Is that correct? Just out of curiosity -- why would that be? Why not let a program set its SPK back to its original state?
