title: Aurelia for.repeat wait spinner
body: <p>I have a really simple test case where I get a large list of Json entries say 2000 items. I simply want to display all these items on one page.
  (Forget about whether that is a good design or not).</p>
  
  <p>I have a standard spinner specified in my index.html that is displayed when loading the page and changing pages. However, the spinner stops and the page is displayed before the for.repeat loop completes.</p>
  
  <p>What is the best way to handle this. I have tried to add a new spinner that page just for the for.repeat but there does not seem to be a way to know when the loop completes. I have tried using TaskQueue without success.
  I could use a setTimeout as a dirty hack but I would like to know the correct way to handle this kind of thing.</p>
  
  <p>Thanks</p>
