Which namespace? PID namespace I presume where we can have a 'new' init
task and everything.

I'm not sure, are any of these things (workqueues, userspace helpers)
pid namespace aware? If not it doesn't seem to make sense to expose this
to nested PID namespaces and would be something special for the root
namespace.
