What does happen with a person's body in space without a spacesuit?

[Pelf41]

If pressure in a vacuum is very low, water can evaporate even at low temperatures, since the lower the pressure, the lower the boiling point.
So, if I were suddenly exposed to the vacuum of space, would my body freeze, or would it expand as the water in my body turned into gas?

Uncontrollable burps and farts: Embarrassing.
Internal gas embolism and colic: Painful.
Accelerated desiccation and freeze drying: Preserving.

Something to consider is that your skin is not merely a bowl of water. It acts a partial barrier to vapourization of water (mucosal membranes notwithstanding). Not a complete barrier, but sufficiently so that a number of other things - relating both to low pressure and extreme cold - will harm you in the meantime.
