Are there any utilities that can be used to see which native (DOM)
objects are being referenced by JavaScript objects, and to follow
references between JS objects to understand what's keeping an object
from being GCd?
(I'm working on reducing Chrome memory usage. One thing I've
discovered is that WebCore::DOMWindow objects (and all their
associated object trees) are sometimes being left behind. JavaScript
seems to be implicated, as the problem goes away if I disable JS. So
something in V8 seems to be holding onto references to DOMWindows, and
I'd like to find out what it is.)
Thanks!
