I am fairly confident that a body floating in space is more likely to freeze, than to explode. I believe floating about at potential temperatures of absolute zero can do that.
Absolute zero my....whatever.
For the millionth time: There is NO TEMPERATURE IN SPACE!
Temperature is a macroscopic term to indicate the internal energy of atoms in a given space.
If there are no atoms, it's pointless to use the term temperature.
Any body in space - including drown pilots - only loose and gain heat through irradiation. Any solid object slowly radiates on the full EM spectrum - loosing heat.
Any body also recieves energy radiated.
If the pilot was on the shiny side of things and close enough to the star (Mercury through Mars distance) he could heat up and eventually evaporate.
In the shadow of something or farther from the sun he would freeze.
It's a matter of heat management or the balance of the recieved and irradiated energy - this is true for any given spacecraft.
This is the reason why the shuttle has to immediately open it's cargo bay once in orbit, since it needs the radiators inside exposed to manage its heat.
As for the boiling blood - it would boil if the it was exposed to space. However it would stay in the pilot's body and therefore remain under pressure (though the blood from his ruptured lungs may evaporate).
