世界	e7a9c90213	Fix DNS cache lock goroutine leak The cache deduplication in Client.Exchange uses a channel-based lock per DNS question. Waiting goroutines blocked on <-cond without context awareness, causing them to accumulate indefinitely when the owning goroutine's transport call stalls. Add select on ctx.Done() so waiters respect context cancellation and timeouts.	2026-02-06 22:28:30 +08:00
