+## NOTE
+
+The library can be safely used only with Go >= 1.10 due to [golang/go#20676](https://github.com/golang/go/issues/20676).
+
+After locking a goroutine to its current OS thread with `runtime.LockOSThread()`
+and changing its network namespace, any new subsequent goroutine won't be
+scheduled on that thread while it's locked. Therefore, the new goroutine
+will run in a different namespace leading to unexpected results.
+
+See [here](https://www.weave.works/blog/linux-namespaces-golang-followup) for more details.
