CoreStep runs SimpleBuildStep.perform in a background thread, via SynchronousNonBlockingStepExecution, so while pending JENKINS-30383 there is a high chance that a Jenkins restart will cause a build failure, at least the CPS VM thread is not blocked. However CoreWrapperStep runs SimpleBuildWrapper.setUp directly from Execution.start, since there is no block-scoped equivalent of SynchronousNonBlockingStepExecution, which means that a slow wrapper could block the VM thread indefinitely.
