	// failure. The number of failures is divided by the number of tasks
	// being updated, and if this fraction is greater than
	// MaxFailureRatio, the failure action is invoked.

	// If the failure action is CONTINUE, there is no effect.
	// If the failure action is PAUSE, no more tasks will be updated until
	// another update is started.
