[JENKINS-41482] Pipeline bat step hangs (after restart)

Pipeline jobs occasionally hang on bat steps. This seems similar to JENKINS-34150">JENKINS-34150 but we are using durable-task 1.12 which has the fix for that.

Thread dump from the job (after 18 hours):

Thread #26

	at DSL.bat(awaiting process completion in C:\j\w\\@​tmp\durable-56b1eae1 on )

	at WorkflowScript.run(WorkflowScript:349)

	at DSL.withEnv(Native Method)

	at WorkflowScript.run(WorkflowScript:242)

	at DSL.stage(Native Method)

	at WorkflowScript.run(WorkflowScript:156)

	at DSL.node(running on )

	at WorkflowScript.run(WorkflowScript:34)

The bat step is running a batch file:

cmd /c call test.bat ....

which in turn is running a python script which (in this case) is throwing an exception (I can see from inspecting log files on the slave). Looking on the slave the "durable-56b1eae1" folder is present with jenkins-log.txt, jenkins-main.bat and jenkins-wrap.bat inside of it. There is no sign of the batch process on the slave so I presume that it has completed. The build continues to occupy a slot on the executor. There are also several flyweight tasks from the matrix plugin on the same slave.

Please let me know if there is anything else I can do to help diagnose this.
