Comment (by arthuredelstein):

 Another thing I want to do for this ticket is to simulate errors in
 various parts of the code, and ensure that we have error handling that
 allows us to log the errors and then gracefully recover. That should help
 avoid the situation where a single error causes the tor circuit display to
 die.
