LOL: U+1F4A9 PILE OF POO. Some fancy terminals might even show it
properly.
And sounds about the right one in this case.

Yeah, we need to think about it. I would be lying if I said I had never
wondered before where a taint flag got set. Saving the address has a
problem when multiple times the same flag gets set - only the last
address will be there.
But I guess we can try it.
/me puts on todo.
