It doesn't give you a hash to crack. It reduces your speed of guessing passwords from "how quick can you hash X", which is millions of times per second, to "how many times can I attempt to get in before the access point blocks me".
This major issue with WPA password cracking today is that it can be done "offline". You can pull the handshake out of the air and bang on it as long as you want. It's pretty much the same thing as trying to guess a password from some leaked hashes vs trying to guess a password using the gmail interface.
