> While running {{mesos-tests}} under Application Verifier, I found that we were inadvertently attempting to get a handle for the System Idle Process. This is not permitted by the OS, and so the {{OpenProcess}} system call was failing. I further found that we were incorrectly checking the failure condition of {{OpenProcess}}. We were attempting to open this handle when opening  handles for all PIDs returned by {{os::pids}}, and the Windows API {{EnumProcess}} includes PID 0 (System Idle Process). As this PID is not useful, we can safely remove it from the {{os::pids}} API. Attempting to do _anything_ with PID 0 will likely result in failure, as it is a special process on Windows, and so we can help to prevent these errors by filtering out PID 0.
