FWIW, GWP just hit one site's root one time, but using three IPs in 2 secs:
UA for all: Mozilla/5.0 (en-us) AppleWebKit/525.13 (KHTML, like Gecko; Google Web Preview) Version/3.1 Safari/525.13
Interestingly GWP only hit root this time, not the two other pages it hit before. And this time, only html and page-unique jpg, not css, gif and png as before.
That pattern sure suggests it's cacheing site-wide css and js.
Last but not least...
Googlebot is disallowed from anything but .html -- and GWP has taken everything but .pdf (thus far). So it appears GWP doesn't regard itself as Googlebot. Or as ANY bot for that matter because it doesn't request robots.txt on its own. If it had, it ideally should've heeded:
