Looks like this test started going bonkers (flip-flopping/random results).

Assigning to owner to take a look...

The private dirty metric became bi-modal. The traces show that the difference is comming from "Files/ttf" bucket:
/System/Library/Fonts/Apple Color Emoji.ttf	000000011fff7000	67,492.0 KiB
/System/Library/Fonts/Apple Color Emoji.ttf	0000000122b49000	244.0 KiB

Sometimes 67MB is accounted as dirty and sometimes only 244KB is accounted as dirty.
