i tested it a lot.

there exists *also* /lib/libc.so besides /lib/i686/libc.so
and killing the /lib/i686 (also /lib/tls) will keep system running, it will 
load /lib/libc.so, if can't find from /lib/i686.

so after the PLD glibc is placed to system, the dir structure could look like

# l /lib/libc.so* /lib/i686/libc.so*
lrwxrwxrwx    1 root     root           13 Oct 24 17:47 /lib/i686/libc.so.6 -> libc-2.2.5.so*
lrwxrwxrwx    1 root     root           13 Oct 24 17:47 /lib/libc.so.6 -> libc-2.2.5.so*

AND the new file is also there:
lrwxrwx---  1 root root 13 Dec  7 21:58 /lib/libc.so.6 -> libc-2.3.3.so*

as there's no newer version in /lib/i686, the symlink stays for old version, 
and eventually it will be /lib/ld-linux.so is from newer glibc and libc from 
older one.

uh. hope it explained it.
