Yeah, that probably won't work. The current code isn't intended to cross jobs like that - I'm sure nobody ever tested it for that idea, and I'm pretty sure it won't support it.
I don't currently know any way to do what you are trying to do. We could extend the signal code to handle it, I would think...but I'm not sure how soon that might happen.
