Fixes: opencontainers#1228

It can be reproduced by applying this patch:
```diff
@@ -45,6 +46,7 @@ func registerMemoryEvent(cgDir string, evName string, arg string) (<-chan struct
        go func() {
                defer func() {
                        close(ch)
+                       <-time.After(1 * time.Second)
                        eventfd.Close()
                        evFile.Close()
                }()
```

We can close channel after fds were closed.
