+can be retrieved and set.  Note that the current namespace is thread local so
+actions that set and reset namespaces should use @code{LockOSThread} to make
+sure the namespace doesn't change due to a goroutine switch.  It is best to
+close @code{NsHandles} when you are done with them.  This can be accomplished
+via a `defer ns.Close()` on the handle.  Changing namespaces requires elevated
+privileges, so in most cases this code needs to be run as root.")
