That is the beneficiary processor “steals idle cycles” from the donor processor. There is a switching time required for the donor processor to start working on the beneficiary jobs,...

The well being of the donor, who derives no medical benefit from this surgery, must be assured in both the short term and long term, and the potential adverse consequences to the recipient must be determined as well.
