Not sure what you mean? If a tame and wild collide; the key is solved. Why do anything else except sweep the funds.
Still, they collide at different times. Probably everything needs to be saved. Very large volume. I launched dp 2^20 and already got 7Gb. I load the starting keys from a file. I save working files every 10 minutes, checking the tame kangaroos for compliance with the secp key-point. The loading and saving code is in the Backup.cpp file.
