  That would imply that the value would be in a global constant, which is
  probably just as practical in many cases, but if you do not know whether
  someone had forked on you since last time, you need to call the system
  function each time you need the value.  It is like asking the system for
  the time of day and hoping to finish your calculation before it changes.
