title: Asking an IntentService for information about its queue
body: <p>I have an IntentService that queues up web service calls that need to be made to my web server.  So each Intent is a web service call to be made.</p>
  
  <p>I'd like to set something up where my application can ask this IntentService if it has any Intents containing a particular piece of data (IE: "Are you already waiting to ask the cloud for x data?  Or do I need to tell you to do it?").</p>
  
  <p>Are there any suggestions on how I might extend IntentService to do this?  Can the Intent queue of an IntentService be traversed?  Or would I need to take the IntentService code and alter it?</p>
  
  <p>The only other idea I have is to add a table to the database and log which calls are in the queue, with each log being removed from the table when completed.</p>
