Apple announces WebKit2, an API (application programming interface) layer for Apple’s version of the WebKit browser engine. Apple’s move may result in a faster future Safari that’s able to use the multiple cores in most modern machines’ processors, analyst says. Google pioneered process separation when it debuted Chrome in September 2008. Chrome uses a separate process for each tab, a practice that helps the browser survive crashes by a plug-in running in one tab or the failure of a Web application in another.”]
