Subject: pid ns feature request

Unless I'm missing some trick, it's currently rather painful to mount
a namespace /proc.  You have to actually be in the pid namespace to
mount the correct /proc instance, and you can't unmount the old /proc
until you've mounted the new /proc.  This means that you have to fork
into the new pid namespace before you can finish setting it up.

Would it make sense to add a mount option to procfs to request a mount
for pid_ns_for_children instead of task_active_pid_ns?
