When does this matter?  I'd like to avoid adding another variation on the
meaning of "GetProcess" if we can.

Initially it was meant to not create a process if there wasn't one. I think in
our pair code review with Nick we analyzed it and concluded that the
HasProcess() check isn't needed and should just return the result of the
GetProcess() call.

Changed.

   }
 
+  // Initializes the object and creates the RenderFrameProxy in the process
+  // for the SiteInstance.
+  bool InitRenderFrameProxy();

   int GetRoutingID() {
     return routing_id_;
