      Per ben.caimano's recent email, task executors are now more aggressive about running callbacks on callers' threads. This means that callbacks should check their provided status argument for whether they're on the caller's thread.

      _handleHeartbeatResponse takes the same mutex that its caller takes. If it runs on the caller's thread, it will deadlock with itself.
