This is separate to the question of "isolated user namespaces" and
managing different mappings between containers. This patchset is solving
the same problem that shiftfs solved -- sharing a single directory tree
between containers that have different ID mappings. rlimits (nor any of
the other proposals we discussed at LPC) will help with this problem.
