title: Detecting Blocked Threads
body: <p>I have a theory regarding trouble shooting a Asynchronous Application (I'm using the CCR) and I wonder if someone can confirm my logic.</p>
  
  <p>If a CCR based multi-threaded application using the default number of threads (i.e. one per core) is slower than the same application with double the threads specified - does this means that threads are being blocked somewhere in the code</p>
  
  <p>What do think?  Is this a quick and valid way to detect if threads are being inadvertantly being blocked?</p>
