Description Chris Dumez 2015-06-01 21:28:36 PDT 
We currently mark layers as volatile when the WebProcess is about to be suspended. Most of the time the WebProcess gets suspended when a page goes into the background. However, it is not always the case (see radar), in which case the layers won't be marked as volatile and waste memory even though they are not visible.

We need to mark layers as volatile as soon as the page goes into the background, instead of relying on the WebProcess suspension mechanism.
