So the challenge here is identifying which subresource loads here we should "convert"
to PingLoader loads. I can't come up with a way to logically identify them. My first
thought was to mark the last "user action" but where does this action start and end.
Take a mouse click for example, there can be loads triggered anywhere in all kinds
of events (onmousedown, onclick, onmouseup) of which WebCore / WebKit only gets
sparse notifications at the WebHTMLView layer. Only on mouseup do we actually
detect a WebCore::handleLinkClick and navigate.

Considering there are already existing solutions for this (<a ping> and performing
the request in pagehide/unload events) I wonder how important it is to detect and
allow these image loads to complete.

Anyone have thoughts on this?
