+ might also change when Windows enlarges the file due to
+ insufficient VM. Still, this seems to be the most reliable way;
+ the alternative (of using GetSystemTimes) won't work on laptops
+ that hibernate, because the system clock is stopped then. Other
+ possibility would be to run "net statistics workstation" and parse
+ the output, but that's gross. So this should do; if the file is
