 // The Windows psapi provides memory information of a process through structure
 // RPROCESS_MEMORY_COUNTERS_EX. Relevant fields are:
 // PagefileUsage: private (not shared) committed virtual space in process.
 //                This is "VM Size" in task manager processes tab.
 // PeakPagefileUsage: peak value of PagefileUsage.
 // WorkingSetSize: physical memory allocated to process including shared pages.
 //                 This is "Memory Usage" in task manager processes tab.
