chroot does not allow you to walk out if you're in.
You're mistaken. Or more properly, further use of chroot lets you walk
out. This really has been said before, and before, and before.
chroot("subtree"); // enter chroot
chdir("/"); // now at subtree
chroot("/tmp"); // now outside of chroot
BSD redefined chroot so that the working directory is set to the new
root on subsequent uses of chroot; that's how they solved the bug.
