How do I display a busy cursor during a route transition in Ember?

What is the best technique to generically change to a busy cursor during transition to a new route in Ember.js (1.13.10)? With data retrieval, this may take a couple of seconds.

The answer here indicates a method to do this with saving data:

Changing mouse cursor while Ember content is saving

...and indicates this is very straight forward with route transitions, but I can't seem to find an example or anything in the documentation.

Thanks in advance for any help on this.
