      pollInterval: 0 is documented as disabling event printing, which EventPrinter honours by skipping its loop. It says nothing about how often the underlying wait should call AWS, and a zero delay there means a tight loop against the API for the whole wait - so a non-positive interval is substituted with one second. Every value that is at least a millisecond is honoured exactly: pollInterval is in milliseconds, so 250 is a legal thing to ask for. The test is on the value in milliseconds, not on the Duration's sign, because both consumers work in milliseconds - Thread.sleep for the stack-set loops, a fixed backoff for the waiters - so a positive but sub-millisecond interval would round to zero there and become the very tight loop this exists to prevent. Pipelines cannot express one (TemplateStepBase builds the Duration with ofMillis), but the guard should not depend on that. Both waiting implementations go through this, so the CloudFormation waiters and the stack-set poll loops cannot drift apart on it.
