Not testing, but more the general stability of the interface. IMHO it exposes
too many kernel internals. I know they are already exposed by clone/unshare, 
but in those nothing breaks if the user program doesn't know about some new
flags. But this looks like the user always has to be updated for every change.
I think I would prefer if more of the user was in kernel to not expose
that much.
