Example of an imo correct way to handle audio sessions in iOS apps with streaming music that will sometimes have pauses between audio playback.

How to wait for multiple different-timed animations in a generic manner? A reply to http://inessential.com/2013/06/22/technical_notes_on_vespers_full-scree .

	#import <SPAsync/SPTask.h>

	@interface UIView (SPTaskAnimations)
