Description

Symptoms: https://issues.apache.org/jira/browse/FLINK-19882?focusedCommentId=17223725&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17223725

Once a test has finished, the timeout watchdog should stop. However it seems that this doesn't always work.
Maybe this is caused by the on_exit trap being overwritten by the test?
