This is how I see it atm
Each tab is a process that is composed of several threads, this process is
sandboxed with the Windows kernel security ( on Windows )
Then we have WebKit which is the rendered thread inside of this main tab
(thread) which as the name implies will render the page.
When in the renderer process is v8 called ?
Or when WebKit is executing UI things v8 is also running JavaScript code ?
Last thing is when ArrayBufferBuilder:append is called ?
