It's automatically enabled, and I don't think it's available for disabling.
I recall hearing something about a feature being added to PHP to help
prevent infinate loops, and it apparently works with print_r.
It should probably be listed more prominately and in any place where
$GLOBALS is mentioned.
The first time I saw it I was thinking, "Geeze, this page sure is taking a
long time to load...and why are so many variables available on this site..."
