Change Details

No test plan. Future diffs will use it.

Temporarily modify NotificationService and AppDelegate so that the first writes notification to a file from which the second reads upon app launch. Cover reads and writes with semaphore operations. Use debugger to hold semaphore in AppDelegate, trigger notification and see that NotificationService did not acquire semaphore (simply logs it).
