Hey @markhamstra, anything specific that you think we should do in case of
more severe errors?
I think it doesn't hurt to handle the failed task in a finally block as
some kind of best-effort to inform the scheduler a task has failed. If some
fatal error prevents us from doing even that much, we probably won't expect to
be able to do anything else.
If we do want to distinguish errors based on level of severity and take
actions accordingly, we can do it as a follow-on task.
