A question for the religiously inclined to ponder..

So I saw this weird thing on slashdot, about how "Pittsburgh's Safar Centre for Resuscitation Research has developed a technique in which subject's veins are drained of blood and filled with an ice-cold salt solution." Apparently they can keep the dogs "dead" for at least 3 hours before reviving them, at which point they come back with not apparent brain/organ damage. They plan to try it on humans sooner or later. So, if the animal/human is dead, where does the soul go during that time? And, if someone had this done, and then wasn't brought back, at what point would they really be dead? Would their soul stick around until the probability of resuscitation was nill, and then head for warmer (or in some cases more temperate) waters? If this is done to a person, and the soul gets kinda confused and takes off too early, will the person be revived a soulless ghola? We need answers from someone with some serious religious training here!
