One warning, a GFI will NOT prevent all possible electrocution hazards. For example if I have on rubber soled shoes on dry surface and get across the hot and neutral with both arms, good chance the GFI won't trip. In this case there likely would not be enough leakage current to a ground to cause an imbalance.
I recall when GFCIs first came out in the 60s I saw a demo on TV where someone held onto a live wire that was connected to one of the newly developed GFCI receptacles and jumped into a pool. He didn't float back to the surface... Could be dreaming or have early-onset dementia tho. Maybe they could try that on Mythbusters and see what happens. :)
