As written above, if that's the main thread, it is guaranteed to freeze in
a deadlock every time. I don't see a goroutine kicked off, so I'm assuming
you're trying to run that on the main thread, and you will be 100%, always,
forever stuck on the `case wch := <- ach {` line.
Channel reads are

I met a problem about etcd watch channel. seems that be closed, but i can
not reproduce it.
like this:
```
for {
ach := etcdClientV3.Watch(context.Background(), "/test",
clientv3.WithPrefix())
for {
select {
case wch := <- ach {
