APP HANG (chrome.exe running close.html under -persist)

it's an app hang: no DR on any callstack

seems to be sort of non-deterministic, but I've only see it happen w/ the new -persist option

still investigating. seems to not happen in debug build which makes it harder.

one theory is the hang is presumably related to invalidating pcaches when loaded: I can more easily make it happen when I generate w/o -persist and then add -persist, which b/c it's marked as a pcache-affecting option ends up invalidating all the pcaches on load. but I can't repro when I do the same thing w/ googleurl_unittests.

I can't repro this on my laptop with either installed chrome.exe or built
chrome.exe. on my windows desktop I can repro with both.
