Thanks for taking a look at this, Alexey. Indeed, the crashes I'm having in MarsEdit are also caused when closing windows. When I saw the same crash in MiniBrowser it encouraged me that it's an issue internal to WebView, WebCore, or maybe NSURLConnection/CFNetwork.

But you're right that the zombie element of the equation is perplexing. I don't think the over-releasing of the WebView happens though unless the problematic web content is loaded into the frame. And I am able to reproduce the problem using a new document-based Cocoa app whose document window has a xib-instantiated WebView that has the problematic content loaded in at nibDidLoad time.

This makes me think that something in the WebKit realm or below is over-releasing the WebView, and maybe the perceived messiness in ResourceHandleMac is not really a problem so long as the WebView sticks around for as long as it should.
