As per `go build -gcflags -m ./... 2>&1`:

Old behaviour:
```
./bucket.go:148:31: leaking param: key
./bucket.go:192:42: leaking param: key
./bucket.go:271:22: leaking param: key
```

Now:
```
./bucket.go:148:31: key does not escape
./bucket.go:192:42: key does not escape
./bucket.go:271:22: key does not escape
```

data race. This patch is to prevent such case and save maintainers' time.
