This message is no longer catch in RenderFrameObserver.

     ContinueProgram();  // Don't want to swallow the message.
 
   return handled;

Why do you need both?  In your comment you mentioned this one might not work.

[dgozman, 2015/03/30 18:43:32]

This one is here just to show what I was talking about. I will remove either one
or another.

Or maybe we should have another notification about "frame will close", but
earlier in pipeline (e.g. when IPC comes)? Because DevToolsAgent does not really
care that widget closes, ViewMsg_CLose just happens to be at the right time.
