No. defer in the SC language and SCVirtualMachine's defer: method are different. If you make any blocking function call from inside the language it will stall the scheduling. Your primitive should post an NSInvocation using SCVirtualMachine's defer: method. Then that deferred method can call URLsFromRunningOpenPanel. When that finishes then you need to call back into the language to have the completion function called. You can get an idea of how this works by looking at prSCWindow_FullScreen, however there is no primitive yet which needs a result returned from a deferred operation like this one does so there is no complete example to do what you need.
