Hi, all. From other user's adivice, partial_sort could be
```
pub fn partial_sort<T, F>(v: &mut [T], limit: usize, mut is_less: F)
where
F: FnMut(&T, &T) -> Ordering,
{
let (before, _mid, _after) = v.select_nth_unstable_by(limit, &mut
is_less);
before.sort_unstable_by(is_less);
}
```
So I abandon to use of custom partial_sort. This could fix the issue and
risk we are arguing about.
