title: Why does the XCode 4 GM console show processes in decimal and threads in hexadecimal?
body: <p>Purely out of curiosity:</p>
  
  <p>I'm doing some UNIX dev in XCode 4 GM and I noticed in the console output that process ID's are being displayed in decimal while thread ID's are being displayed in hexadecimal.</p>
  
  <p>Example:</p>
  
  <pre><code>[Switching to process 37574 thread 0x0]
  </code></pre>
  
  <p>Why are these conventions used ?</p>
  
  <p>Thanks,</p>
