I put "pauseless" in quotes because I know it's not entirely pauseless. It's described as "ultra low pause time" by the original project.
However, whether we like it or not, Azul has established the term "pauseless" as the way to describe their own collector which before Shenandoah was the only GC that can realistically be described that way, and which Shenandoah is very similar to. This is despite the fact that Zing still pauses. Specifically, the GC moves objects whilst the program runs.
I am unaware of any GC algorithms that are truly, completely pauseless in every situation. So I don't know what you want the term to be reserved for.
