Stop the prune thread and the upload thread when moving to the inactive/background state. This will reduce the number of 0xdead10cc system kills from having a file lock during iOS suspend. Wait to start the prune thread when the application is active. Otherwise, for iOS prewarmed applications, the prune thread will regularly start when the application is foregrounded for the first time when the user intentionally runs the app. It's still possible for either the prune thread or the upload thread to have a file lock during iOS suspend, such as when a task started in the foreground and does not complete in time for suspension. Future work should include considering BackgroundTasks and/or NSURLSessions, which can more safely run in the background.
