This is a heads-up that we will shortly start landing patches for a new WebKit framework that we at Apple have been working on for a while. We currently call this new framework "WebKit2".
WebKit2 is designed from the ground up to support a split process model, where the web content (JavaScript, HTML, layout, etc) lives in a separate process. This model is similar to what Google Chrome offers, with the major difference being that we have built the process split model directly into the framework, allowing other clients to use it.
Some high-level documentation is available at http://trac.webkit.org/wiki/WebKit2
Currently WebKit2 is available for Mac and Windows, and we would gladly accept patches to add more ports.
