We have had this conversation multiple times in the past, and version
1 of our application lifecycle will not allow to run arbitrary
applications in the background. Instead, we will provide selected
services to hand over to the system for certain tasks, e.g.,
downloads, alarms, music playback. Please note that this is a policy
targetted towards the "mobile phone" usage scenario and swapping
policies at runtime when transitioning to different usage scenarios is
one of the primary goals of the lifecycle architecture.

Version 2 of the lifecycle will then allow applications to run their
own background tasks, UI less, with restrictions on
CPU/Memory/resources in general.
