If priorities range from 63 (low) to 0 (high), we could increase the priority of a waiting process by 1 every 15 minutes. Eventually, even a process with an initial priority of 63 would have the highest priority in the system and would be executed. In fact, it would take no more than hours for a priority-63 process to age to a priority-0 process.
