[JENKINS-73839] Pipeline hangs if process killed

[jenkins-infra-bot]

We have observed that if a powershell process launched by a Jenkins pipeline is killed, the pipeline execution will hang indefinitely or a job timeout is reached.

To reproduce, you can create a pipeline that runs a powershell script that logs something, sleeps, then logs something else. If the powershell process on the agent is killed during the sleep, you'll see the job hang and never log the second log.
