Title: Needs Feedback: try do do something with a heartbeat error.

The heartbeater can throw an error at any time. This fix assumes that the session is ruined if the heartbeat returns an error.
* report that error to the client
* client turns off the heartbeat

Nothing gets done after that though, which troubles me. At some point the client should notify its owner that bad things have happened.
