==================
```

The schedule for compact is handled asynchronously and it might use
`t.Logf` after go-test marks the case is done. And there is a comment
from go-test:

```go
// c69ff3a7d0/src/testing/testing.go (LL1580C3-L1582C16)
                // Do not lock t.done to allow race detector to detect race in case
		// the user does not appropriately synchronize a goroutine.
		t.done = true
```

We need to ensure that all the goroutines should be closed before case
finish.
