Don't think so, for the Postscript function thing we are caching 5 items/keys

The key is a bool, a int and an array of doubles, usually smaller than 5 
(though it's the input parameters of the function and probably can be bigger).

The item is a int and an array of doubles, that is usually 4 describing a 
color.

So it's less than for the particulary slow PDF i have around it's around 500 
bytes.
