title: NSURLConnection synchonous methods from within NSOperation
body: <p>Suppose I have multiple NSOperation objects attached to a concurrent queue.</p>
  
  <p>Within these NSOperations, I would call a synchronous method of NSURLConnectionClass, <code>sendSynchronousRequest ...</code> just to not mess up my code with tracing different connections from within a single delegate.</p>
  
  <p>Apple says that <code>sendSynchronousRequest ...</code> is going to automatically create a separate thread with a run loop to trace NSURLConnection delegate messages.</p>
  
  <p>But I already have several additional threads (running inside <code>NSOperation</code>)! So the question is: if I have, say, 10 <code>NSOperation</code> objects and each would call the synchronous method of <code>NSURLConnection</code>, will it produce 10 more additional ("automatically created") threads with run loops or there will be only <strong>one</strong> for all of them?</p>
