> 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.
