What happens to astronauts when they rip their glove while on a spacewalk?

He would have died dummy - what do you not understand about the vacuum of space and the fact that humans cannot live without oxygen and being full of gas will die in a vacuum?

he would be vacuumed

his lungs would have instantly collapsed and his blood would have begun boiling. He would have died instantly.

The loss of pressure would have been noticed and he/she would have got back into the space station as quick as possible. They would probably survive as long as the leak was not too fast.

he would of become a permanent addition to the satellites orbiting this plant.

If they just cut the first layer, and even the second layer, they don't have anything to worry about.
But if the cut the layer that hold the pressure in their suit, their blood will boil into a gas, if you would like to see what this would be like, take a hot Coke and shake it up, then open it, that is what their blood would do, depending on how fast the pressure go out of the suit.
And nearly every vain in their bodies would explode from this.

Well, the previous posters are being melodramatic.  I think they've all seen those Sci Fi movies where a guy's head explodes after he gets sucked out of a space capsule.  

From what I've read, it's not that extreme.  Yes, your blood will boil eventually, but your body has enough internal pressure to last a minute or so -- it's definitely not an instantaneous and gruesome death.  So, if the astronaut realized something was wrong (and it seems likely a weird sensation would crop up very quickly), I think he'd have time to get back to safety.

His hand would have frozen solid after his blood boiled away! When you have an absolute vacuum you have intense suction. It doesn't take long for the tiny amount of atmosphere inside a persons suit to be released to the outside when exposed to absolute vacuum! One pilot had a faulty glove in a high altitude test and he had severe injuries to his hand before they could get him back on the ground!

He would probably com-bust. That spot would have frozen, after him boiling. I hate to even think about it.
