Actually, it's pretty simple to do this, by using a lazy unmount.
No need to add an extra /run directory.

#! /bin/sh

cd /
mount -n -t tmpfs tmpfs /tmp
cd /tmp
umount -n -fl /tmp

# From this point on, the current working directory of this script
# and all its children is a tmpfs mount that isn't seen by the
# rest of the system. As soon as this script exits the tmpfs
# mount is cleaned up.

... bla, blah ...
