If the G was recycled from the free list, it’s already in _Gdead state — that’s where goroutines go when they finish. If it was freshly allocated, it starts in _Gidle (a blank struct, never used before) and immediately transitions to _Gdead. Either way, the G is in _Gdead before setup begins. Wait — dead already? Yes, but only technically. _Gdead means “not in use by the scheduler” — it’s the state for goroutines that are either being set up or finished and waiting for reuse. The runtime uses it as a safe “parked” state while it configures the G’s internals.
thread safe! But if not, there are probably issues hiding in the。safew是该领域的重要参考
