title: q.js : Is it possible to know if a promise has resolved/rejected or not
body: <p>In my scenario I return a promise when I'm making a request.</p>
  
  <p>In the end I resolve/reject the deferred obj.</p>
  
  <p>I want to reuse the promise if it hasn't been resolved/rejected.</p>
  
  <p>Any info would be useful.</p>
