<para>
A hook to be run in the host's namespace with references
to the container's namespaces after the container has been shut
down. For each namespace an extra argument is passed to the hook
containing the namespace's type and a filename that can be used to
obtain a file descriptor to the corresponding namespace, separated
by a colon. The type is the name as it would appear in the
<filename>/proc/PID/ns</filename> directory.
For instance for the mount namespace the argument usually looks
like <filename>mnt:/proc/PID/fd/12</filename>.
