First, a bit of operating-system design context. Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping? If multiple threads can synchronize or coalesce their timer waits then the system becomes more power efficient.
