Neil, this looks legit to me. Apparently some config var is assigned to another
var somewhere and manipulated later, but because of the by-reference nature of
array assignments in JS, this ends up manipulating the config itself, which is
kind of evil and apparently leads to pollution. The proposed fix (there's no
patch but see comment #6) is to clone the array with something like var bar =
$.extend( {}, foo ); instead of var bar = foo;
