First, a bit of operating-system design context. It is desirable for a program to be able to go to sleep and then wake up a little while later. 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?

The diagnosis is that file notification buffers are allocated out of pool memory ( ExAllocatePoolWithTag ) and then filled with the available notification data. If the notification system knew that the incoming memory was already zeroed then it wouldn’t need to zero it, and it wouldn’t get faulted in, and life would be much better.
