Dear All,
Is the arc GC a rewrite of mimalloc? araqsgc is based on mimalloc (https://github.com/Araq/araqsgc) but I don't know whether it's the same as arc...
Mimalloc is a dropped experiment to plug Nim's GC into Mimalloc provided hooks to amortize GC cleanups by running them as the same time as Mimalloc cleanups.
Arc is different.
