> There are paths through WorkManager and Foreman that will allow a Drillbit to
> get wedged if there are failures. This can happen because events delivered
> via other threads will get stuck if Foreman throws an exception before it is
> accepting external events.
> This is a call to do some general cleanup here and make drillbits more robust
> so that they don't hang when there are query failures.
