MULTIPLE_SECONDARY_PROCESSES

Use one process for each WebView, while still allowing for some of them to share a process in certain situations.

The main advantage of this process model is that the rendering process for a web view can crash while the rest of the views keep working normally. This process model is indicated for applications which may use a number of web views and the content of in each must not interfere with the rest — for example a full-fledged web browser with support for multiple tabs.
