Comment (by hellais):

 So looking back at actually properly fixing this and not just making a
 workaround, I realised that the true issue lied in the fact that a full
 page-re-render was being done every time a relay was being looked up.

 This obviously lead to terrible performances.

 By delaying the rendering of the page of results until all the relays have
 been looked up there is a noticeable performance benefit:
 https://github.com/hellais/atlas/commit/4da8ad27333efb72eddcc69bad5fb42c15b740bc.

 I think there is probably a better way of doing this by leveraging by
 doing some two-way data binding in backbone (in angular this is quite
 trivial to do, but in backbone there a slight bit more work to do it
 properly: see: http://stackoverflow.com/questions/12604834/two-way-data-
 binding-in-backbone-js)
