	//		the given list have fired their own deferreds.  The parameters `fireOnOneCallback` and
	//		fireOnOneErrback, will fire before all the deferreds as appropriate
	// list:
	//		The list of deferreds to be synchronizied with this DeferredList
	// fireOnOneCallback:
	//		Will cause the DeferredLists callback to be fired as soon as any
	//		of the deferreds in its list have been fired instead of waiting until
	//		the entire list has finished
	// fireonOneErrback:
	//		Will cause the errback to fire upon any of the deferreds errback
	// canceller:
	//		A deferred canceller function, see dojo.Deferred
