Is it worth 52 seconds to get a call right?

In the 11th inning of yesterday's Dodgers/Rockies game, Rafael Furcal grounded into what looked like a double play but was called safe.Jim Tracy came out to argue and less than a minute after the play was made, the instant replay showed that Furcal was indeed out.It was 52 seconds.All the people screaming "it will slow down the game" need to answer to this.Less than a minute later we saw the call
