> The implementation depends on elements always arriving in a round-robin
> fashion, i.e. element from first input, then element from second input, then
> first again and so on (read order is 1,2,1,2...). I don't think this
> assumption holds for real-world problems.
> For example, CoWindowTest produces wrong results if MockCoContext is modified
> to read two elements from input 1 and then one from two (read order
> 1,1,2,1,1,2...).
