See pre-emptible as something that should only run jobs that can be re-schedule. You don't save what you're doing; you close all that can be closed and mark all tasks that have to be re-done. If you are 3 minutes in a task that takes 5 minutes, then stop it and put it back on your global queue; The gain of running on preempt will compensate for the loss of rerunning a few tasks twice.
