奇数と偶数を交互に出力するゴルーチンがデッドロックに陥る

func main() {
    even := make(chan bool)
    odd := make(chan bool)
    go func() {
        defer close(odd)
        for i := 0; i <= 10; i += 2 {
            <-even
            print("even ====>")
            println(i)
            odd <- true
        }
    }()
    var wait sync.waitgroup
    wait.add(1)
    go func() {
        for i := 1; i <= 10; i += 2 {
            _, ok := <-odd
            if !ok {
                wait.done()
                return
            }
            print("odd ====>")
            println(i)
            even <- true
        }
    }()
    even <- true
    wait.wait()
}
