On unix systems I tend to use find a lot, and in ways that aren't
easy to replicate with du.  Anything even slightly complicated,
say combining -prune, -type, -newer, and -exec, is nearly impossible
to do in a correct and efficient way without find, even if you have
an xargs.  I'm not sure I understand the resistance to having a
find command in plan9.
