      Description

        Some of our users like some properties of the marking/traversal behaviour of the Traversal mode, but would also like the benefits and ergonomics of the normal mode. It turns out that it is relatively easy to transplant the barrier-model of Traversal mode into the regular mode. This is essentially a variant of the well-known incremental-update model of concurrent marking.
