Variants

Atomic = 0

Atomic stop-the-world marking. This option does not require any write barriers but is the most intrusive in terms of jank.

Incremental = 1

Incremental marking interleaves marking with the rest of the application workload on the same thread.

IncrementalAndConcurrent = 2

Incremental and concurrent marking.
