title: Xcode suddenly becomes very slow
body: <p>My Xcode speed has come down to a crawl. I have no idea why. CPU activity is very low on both cores, gobs of memory.</p>
  
  <p>It's almost as if it's waiting for something but I have no idea what. I have disconnected all USB and FireWire devices but it helped only a little bit.</p>
  
  <p>Any ideas?</p>
