-----------------------------------
It has a problem.
{code}
public class KeyLocker<K extends Comparable<? super K>> {
{code}
KeyLocker require the the {{K}} is {{Comparable}}, But key in
{{ConcurrentIndex}} has no constraint.
> Race condition in ConcurrentIndex

> {{ConcurrentIndex.put}} and {{remove}} are in race condition. It is possible
> to remove a non-empty set, and to add a value to a removed set. Also
> {{ConcurrentIndex.values}} is vague in sense that the returned set sometimes
> trace the current state and sometimes doesn't.
