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. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
