Hi Wit,

Why do you need to kill the old suspension? Is it because the
state you calculate is stored in the suspension, and it has
changed? If so, you can use setarg/3 to change the state and
use demon suspension. This will only work if your state does
not need to survive backtracking.

Cheers,

Kish
