Whoops, it doesn't like it much; I was hoping for a warning but it produced 
an abort instead.  Your suggestion below should work nicely, though.

| 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

The only real problem with this is if it's done twice without an intervening 
reboot then things will fall over as happened to Max; that's why I stressed 
that while a reboot isn't essential, it's a good idea.  But if for some 
reason it's not possible to reboot immediately, one can run indefinitely as 
long as they don't try to replace getcwd.so again (or they can rename it to 
something else in step 2, so /lib/getcwd.so.old is still untouched).
