body: <p>How can I display all the threads for my program when debug in Xcode?
  I am using eclipse for java debugging, it can show all the current threads in the program
  and I can suspend each one of them and show their current stack trace.  Can I do that same in XCode?</p>
  
  <p>Thank you.</p>
