I don't think is unlikely at all to enter in a low memory scenario when webkit is idle.
Just suppose that the user minimizes the browser and loads up libreoffice or any other application.
In that situation webkit should be able to get the memory pressure notification as fast as possible and free the caches potentially keeping the system from swapping.</pre>
