If you're using the same Perforce checkout script we are (from the Perforce web site), I tracked the problem down to the line where the script tells Xcode to show the feedback dialog:

osascript -e "tell application \"xcode\" to display dialog 
  (system attribute \"XC_RES\") buttons {\"OK\"} default button 
  1 giving up after (system attribute \"XC_TO\")"

Setting fb=0 disables this functionality, so you don't get the confirmation that the checkout was successful, but you don't get the hang either.

The same osascript command works fine for me from Terminal, not sure why Xcode has a problem with it running in this context. I can do without the feedback, so didn't track it down any further.
