It's possible that an AsyncHandler could have a re-submitted to it if one of it's child handlers produces a log. This causes the queue to potentially fill up. We should check if a record comes from a the worker thread and take action on the record. The options seem to be:

1. Ignore the record
2. Pass the record through publishToNestedHandlers(). Note that this approach will block an AsyncHandler so this might not be ideal. However, it allows the subhandler to take action on the record.
