What lives there? First, the global run queue (runq) — a linked list of goroutines that aren’t in any P’s local queue. These are goroutines that overflowed from a full local queue, or that came back from a system call and couldn’t find a P. There’s also a global free list (gFree) of dead goroutines waiting to be recycled — when a P’s local free list runs out, it refills from here, and when a P has too many dead goroutines, it dumps some back. The same two-level pattern we saw in the memory allocator: local caches for the fast path, shared pool as backup.
