Re: The kind of leak.
At Le Bourget, astronaut Jean-Pierre Haigneré was asked a question about leaks in a spacesuit. (He spent 6 months aboard Mir in 1999 and had an EVA).
If you have a crack or a leak on the helmet, you die within seconds (he disagrees thus with ACC in 2001 (the movie)). However, if you have a leak on a glove, if the fabric is squeezed at the wrist (something the astronauts can initiate), it is possible to survive up to 15 minutes in vacuum.
