But upon reflection, I do not believe that the kernel is adding value

User-space can do this for itself (and in the case of desktop distros,
already does),
and so the kernel should butt-out.

There is however a race condition with doing it in user space.
So adding a parameter to select behavior would increase safety a bit.
