I'm not yet certain this fix is the root cause of the stalling tests
mentioned in https://issues.apache.org/jira/browse/FLINK-8283. It's something I
stumbled across while investigating the failing tests.
Will run several local Travis runs over a period of time to see if the
stalling tests still occur.---
