This pops out every now and then in different contexts: recursive
delete, recursive copy, (and now) recursive chowning...

I wonder whether a unified implementation would be possible, e.g.:

recurse(dir) do |item|
  File.delete(item)
end


Find.find is very similar, though it first visits directories and then
their content (preventing to delete directories), and does not change
the current dir.

Ideas?
