Thank you. My reading of that is that the algorithm is theoretically pauseless, but the implementation has a fixed sub millisecond pause that doesn't scale with heap size or allocation rate. So they could make the implementation truly pauseless, but it wouldn't make any practical impact because of other factors like CPU scheduling jitter dominating. So to all intents and purposes it is pauseless.
