There have been directories that had been extracted with mode 415 (or 
similar, at least non-executable for the user). These directories also 
had subdirectories.

mkdir dir
mkdir dir/subdir
touch dir/subdir/file
chmod 123 dir/subdir/file
chmod 444 dir/subdir
chmod 400 dir

When find(1) iterated over such a directory, it couldn't change to the 
subdirectories to fix their permissions, too, because the directory was 
still non-executable at that point.

$ find . -print
