- Rename run_once! to find_and_handle_events!
- Extract loop contents into run_once!
- Reuse sleep_break in arbitrary_sleep
- Remove now-redundant exit? check
- Use exit! to set @exit due to error
- Now we can avoid calling run! in specs to avoid excessive stubbing

If the first error was over 30 minutes ago,
and there were no successes after that,
then the next error will cause the loop to exit.
