Looks like a bugfix for a separate CL?

[Sami, 2016/03/21 19:16:29]

Done (landed separately).

   state->SetInteger("registered_delay_count", delayed_wakeup_multimap_.size());
   if (!delayed_wakeup_multimap_.empty()) {
     base::TimeDelta delay = delayed_wakeup_multimap_.begin()->first - Now();
     state->SetDouble("next_delay_ms", delay.InMillisecondsF());
   }
-  state->EndArray();
   AsValueIntoInternal(state);
   state->EndDictionary();
 }
 
 }  // namespace scheduler
