      Description

      On Windows, we are calling the Windows API GetProcessMemoryInfo() and returning the PageFaultCount as serverStatus.extra_info.page_faults. This value is the sum of "soft" and "hard" page faults, which makes the value not directly comparable with Linux and other OSs. We should instead report only "hard" page faults: page faults that cause a read from the page file or other file (such as a MongoDB database file).
