NsHandles can be
+retrieved and set.  Note that the current namespace is thread local so actions
+that set and reset namespaces should use LockOSThread to make sure the 
namespace
+doesn't change due to a goroutine switch.  It is best to close 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.")
