File: controllers/load.js line 45
By eric-wang:

load method will return a load deferred object.
Because controller is driven by trigger event and cannot return the deferred object to the event caller(who trigger the event), so it's better to save the deferred object on the dojo.Evented instance and all controller can share this instance.
