Abstract: Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, an application that may normally be placed into the background state may instead be terminated if it controls a lock on a shared system resource.

Abstract translation: 提供个人电子设备的服务，支持后台处理或多任务的形式。 所公开的服务允许用户应用程序利用后台处理，而不会对用户对前台进程或个人电子设备的电源资源的体验产生显着的负面影响。 为了实现所公开的多任务，可以执行一些或多个操作限制。 作为示例，如果控制对共享系统资源的锁定，则通常可以放置到后台状态的应用可以被终止。
