      Description

      Nathan had fixed the dining philosopher problem by putting a overflow buffer in the spout so that spout is not blocking. However, overflow buffer is not used when emitting the metric, and that could result in the deadlock. I modified the executor to use overflow buffer for emitting metrics and afterwards topology didn't hang.
