we explored how Go’s memory allocator manages heap memory — grabbing large arenas from the OS, dividing them into spans and size classes, and using a three-level hierarchy (mcache, mcentral, mheap) to make most allocations lock-free.

That’s the scheduler’s job, and that’s what we’re exploring today.
