Description

If BackgroundPipelineCreatorV2 tries to trigger one-shot run while pipeline creation is in progress (before entering wait()), then its notifyAll() call is lost. This can result in unnecessary wait, as it will only check if it needs to run after the wait is over.

I think this may contribute to tests timing out waiting for SCM safemode exit.
