| <div class="block">Manages the end-state processing for Foreman. |
| |
| End-state processing is tricky, because even if a query appears to succeed, but |
| we then encounter a problem during cleanup, we still want to mark the query as |
| failed. So we have to construct the successful result we would send, and then |
| clean up before we send that result, possibly changing that result if we encounter |
| a problem during cleanup. We only send the result when there is nothing left to |
| do, so it will account for any possible problems. |
| |
| The idea here is to make close()ing the ForemanResult do the final cleanup and |
| sending. Closing the result must be the last thing that is done by Foreman.</div> |
