If your find is POSIX conforming, then you can do

find / -owner $old_uid -exec chown $2 {} +

and this is the same as the xargs with the -print0 and -0, and more
portable! It does NOT do unnecessary large numbers of single-instance
exec calls! Note that the last argument is "+" and not "\;" ...

Note that GNU findutils has supported this for over two years.
