Can we, maybe in a follow up, replace |message_loop| with a bool? I think all
the callers pass in base::MessageLoop::current() or nullptr.

-      message_loop->RunUntilIdle();
+      RunLoop().RunUntilIdle();
     }
   }
   TimeDelta elapsed = timer.Elapsed();
   // If DCHECK is ever hit, check if |action| is doing something that is
   // taking an unreasonably long time, or if |condition| does not come
   // true quickly enough. Increase |timeout| only if necessary.
   DCHECK(!condition || condition());
   return elapsed;
 }
