If we want to do something like this the only sane thing I can see is to
have a per container version of kthread call it uthread.  That the user
mode helper code would use to launch a new process.

Anything else and I expect we will be tearing our hair out for the rest
of our lives with weird corner cases or unexpected semantics.

At first glace I would exepct uthread to be per pid namespace in
implementation.
