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.
