That description was extreme in its paranoia. :-)

What happens if /etc/ld.so.preload references a non-existant file?
Does it handle that?  Otherwise, my suggestion was:

1. mv /etc/ld.so.preload /etc/ld.so.preload.foo
2. mv /lib/getcwd.so /lib/getcwd.so.old
3. cp getcwd.so /lib/getcwd.so
4. mv /etc/ld.so.preload.foo /etc/ld.so.preload
