[JENKINS-38713] timeout failing to terminate run-away Pipeline executions

In this Jenkinsfile we're using a timeout block to prevent run-away test executions which would waste our cloud budget.

It appears that this fails to actually stop executions.in some circumstances that I have not yet determined.

I captured the following thread-dump from the Pipeline execution:

Thread #12

	at WorkflowScript.run(WorkflowScript:21)

	at DSL.node(running on Azure1003041313)

	at WorkflowScript.run(WorkflowScript:20)

I don't yet have a reproduction case, as I see this only sporadically, but I see it at least once or twice a week on ci.jenkins.io so if there are additional diagnostics I can perform the next time I see the issue, please let me know!
